Milan's remarkable trees are rarely medieval; the city rebuilt itself too many times, and around itself even more, for old wood to survive by accident. What lasted here did so because an institution kept records (a university's ginkgo pair, brought from China in 1775), a neighbourhood organised (a paulownia a Brera committee saved from a car park in 2016), or a park changed its job entirely (a horse-racing track that became a school for sick children in 1919 and kept its oaks). Thirty trees, and almost every one owes its survival to a specific human decision.

Il Sacerdote
Bald Cypress (Taxodium distichum) · approximately 156 years · Porta Venezia
For years, gardeners in Porta Venezia's park called this tree a metasequoia and had the genus wrong before anyone checked properly. It is in fact a bald cypress, one of the first ever planted in Milan, native to the swamps of the American South rather than to any part of Italy, and one of very few conifers anywhere that drops its needles for winter, the trait that gives the whole species its English name. Standing roughly 35 metres tall with a trunk 6.2 metres around, it grows at the edge of the artificial lake inside the Giardini Pubblici Indro Montanelli, Milan's oldest public park, opened in 1784 on land a Habsburg duke gave up for prisoners to landscape. Other cypresses share its stretch of water, but this is the tallest and widest of the whole stand, the reason the Milanese writer and forest scholar Tiziano Fratus nicknamed it Il Sacerdote, the priest, for the way its bare winter branches spread like a robe. Its roots, like those of every bald cypress in wet ground, throw up woody knees above the waterline to breathe, a feature visitors often mistake for stumps. At around 156 years old it predates the park's nineteenth century English-garden makeover and has outlasted the zoo that once shared these grounds, dismantled in 1992.

Platano di Indro
London Plane (Platanus x acerifolia) · age undocumented, likely 100-240 years · Porta Venezia
The largest plane tree in Milan does not grow tall so much as it grows sideways, in every direction at once. Named for Indro Montanelli, the journalist the park was rededicated to in 2002, it stands about 50 metres from his statue with a trunk 8.36 metres around, the widest of any plane in the city, rising from a short, irregular, deeply fluted base that splits almost at ground level into at least five major limbs, each thick enough to be a trunk of its own. The effect, according to arborists who have surveyed it, is closer to a vase held open than to the single straight column most plane trees grow into. No planting record survives, ordinary for a park redesigned twice since 1784 and never catalogued tree by tree until recently, so its age can only be guessed at from girth: somewhere in its second century, possibly its third. What is documented is who lives in it. Ring-necked parakeets, an escaped-pet species now breeding wild across Milan, nest in cavities high in the crown, adding flashes of tropical green to a tree already too disorderly to look properly manicured. Visitors chasing the statue for a photograph rarely look up at what is standing over it.

Bagolaro dei Giardini Montanelli
Mediterranean Hackberry (Celtis australis) · approximately 164 years · Porta Venezia
Milan calls this species spaccasassi, the stone-splitter, for roots strong enough to crack paving, and this hackberry has had over a century and a half to test the claim against the paths of the city's oldest public park. Standing 27 metres tall with a trunk 4.24 metres around, it is one of seven trees the city has formally recognised as monumental within the Giardini Pubblici Indro Montanelli, sharing that status with the plane and the cypress a short walk away. Celtis australis is native across the Mediterranean and was planted widely in nineteenth century Milan for the same reason it thrives today: almost nothing bothers it, not soot, not drought, not the compacted soil under a park crossed by tens of thousands of people a week. Its small, dark, cherry-like fruit ripens in autumn and draws blackbirds rather than people, who mostly walk past a tree with none of the visible drama of its more contorted neighbours. Italy's monumental tree registry puts its age at 164 years, calculated from growth data rather than any surviving planting record, the only figure any source gives; treated here as an estimate rather than a settled fact.

Il Ginkgo dell'Orto Botanico di Brera
Ginkgo (Ginkgo biloba) · approximately 235-251 years · Brera
Behind Palazzo Brera's courtyard grows a pair of trees older than the idea of Italy itself: a male and a female ginkgo, planted together in 1775 when Empress Maria Theresa's new botanical garden was barely a year old, grown from seed carried directly from China less than two decades after the species had reached Europe at all. Ginkgo biloba is often called a living fossil, essentially unchanged for over 200 million years and the sole survivor of a family that once grew alongside dinosaurs; this pair is a comparative sapling by that measure, but at somewhere between 235 and 251 years old, depending on whether growth-ring calculation or the garden's own planting record is trusted, they are the oldest documented trees in Milan by a wide margin. In March 2026 the university marked their joint 250th anniversary with a public conference built entirely around the two trees. Every November their fan-shaped leaves turn a uniform gold and drop within days rather than fading gradually, briefly carpeting the beds around them. Entry to the garden is free, a rarity among Milan's oldest sites, down a courtyard most visitors to the Pinacoteca next door never think to enter.

La Catalpa della Guastalla
Southern Catalpa (Catalpa bignonioides) · approximately 136 years · Guastalla
Milan's oldest public garden, laid out in 1555 for a countess who did not live to see it finished, keeps its strangest tree behind a baroque fish pond nobody expects to find in the middle of the city. This catalpa, a North American species imported to Europe for ornamental foliage rather than any practical use, has spent roughly 136 years twisting instead of growing straight, until arborists describe its 3.5-metre trunk as closer to a piece of vegetal sculpture than an ordinary shade tree. Every June its crown fills with white, orchid-patterned flowers in dense upright clusters, followed by the long, thin seed pods that earned the species its American nickname, the cigar tree. The Giardini della Guastalla itself predates almost everything else on this list: founded by Ludovica Torelli, Countess of Guastalla, as a garden for the girls' college she funded, it became one of Milan's first public parks open to all, four centuries after her death. At just over 12,000 square metres it is one of the smallest gardens on this list and one of the easiest to walk past, a few streets from the university hospital rather than fronting any grand piazza.

La Quercia Rossa di Piazza XXIV Maggio
Northern Red Oak (Quercus rubra) · approximately 131 years · Porta Ticinese
This oak was already growing in an American nursery when Milan was still deciding what to do with the site of one of its six historic gates. Giunio Capè had the sapling brought to Piazza XXIV Maggio at the end of the First World War and planted it in 1924 in memory of his son Giuseppe, an Alpine soldier who survived the war, and of the Alpini who did not. A century later the oak stands nearly 20 metres tall with a trunk just under 5 metres around, held up since 2019 by a discreet steel exoskeleton a Bergamo carpentry firm built to support a crown that had begun to outgrow its own structure. Quercus rubra is native to eastern North America and turns a deep, almost oxidised red in October and November, the colour that gives the species its name and, briefly each autumn, the only real red in a square better known for the nineteenth century customs arches of the old Porta Ticinese behind it. Milanese press sometimes calls it the oldest tree in the city; it is not, several trees on this list are older, but it may be the only one whose exact planting date and reason for standing there are both on record.

La Quercia Rossa del Trotter
Northern Red Oak (Quercus rubra) · approximately 85 years · Trotter, Municipio 2
This oak grows on a horse-racing track that stopped racing a century ago and became a school instead. Parco Trotter takes its name from the Società del Trotter, which ran harness races here from the 1800s until the track moved to San Siro in 1924; when the sporting company folded, Milan's city council bought the abandoned oval and turned it, starting in 1919, into Casa del Sole, a 128,000 square metre open-air school for children with tuberculosis and other chronic illness, built on the belief that fresh air and space were themselves a treatment. The ring shape of the old racetrack still defines the park's paths today, cut across by a single straight avenue of plane trees. This red oak, planted not long after the school opened, now stands about 40 metres tall, taller than any other tree on this list, with a trunk 4.3 metres around, growing beside Via Giacosa near the park's old chapel. The school never fully closed. Children still attend classes on these grounds, which is why the park keeps unusual hours, open to the public only outside school time, free every day it opens rather than at any point in between.

La Paulownia di Via Madonnina
Empress Tree (Paulownia tomentosa) · over 65 years, exact age undocumented · Brera
Milan's most photographed tree grows on a triangular scrap of land where a building once stood, until Allied bombs brought it down during the Second World War. Nothing was rebuilt on the corner of Via Madonnina and Via San Carpoforo, and sometime in the decades after the war a paulownia took root in the cleared gap, on land nobody had any particular plan for. By the 2010s the plot had become something else entirely: probably the most photographed tree in the city according to local press, its lilac flowers a fixture of every spring guide to the Brera district. That popularity is the only reason it still stands. A developer held rights to build a small residential block on the triangular lot, and only a sustained campaign by Brera residents, who formed a committee specifically to save the tree, persuaded Milan's city council to acquire the 155 square metre plot in 2016 in exchange for a larger site elsewhere in the city. The paulownia survived a violent storm in July 2023 that uprooted an old fig tree growing beside it. No scientific study has ever aged it precisely; residents describe it as over 65 years old, grown entirely on its own rather than planted by anyone with a plan.

La Pianta di Affori
London Plane (Platanus x acerifolia) · 187 years by dendrochronological analysis; local tradition claims over 250 · Affori, Municipio 9
Every Milanese from Affori knows this tree simply as la Pianta, the Plant, as if there were no other, and local legend insists Napoleon is the reason it stands where it does: supposedly planted to honour a Milanese noblewoman he had fallen for during his Italian campaign, sometime around 1800. Core samples taken in 2013, when a restoration crew drilled into the trunk to check its health, tell a more modest story: growth rings put the tree at about 187 years old at the time, closer to the 1820s than the Napoleonic Wars. This page gives both figures, since neither can be disproved outright and the drilled sample is the harder evidence. What is not in dispute is the tree itself: a plane 20 metres tall with a trunk over 2 metres in diameter, standing at the corner of Viale Affori and Via Astesani since before the surrounding neighbourhood existed as anything but farmland. An owl once nested in a cavity on its western side; the memory is marked today by a small wooden owl sculpture at the base of the trunk. A metal bracket further up the trunk, once used to string electrical cable through the branches, is a rare surviving trace of how Milan wired its outer suburbs before anyone thought to protect the tree carrying the load.

Il Noce del Caucaso di Parco Sempione
Caucasian Wingnut (Pterocarya fraxinifolia) · age undocumented · Sempione
This walnut grows almost horizontally over the water, its lower limbs bending so far toward the pond in Parco Sempione that locals joke it is trying to drink from it. Pterocarya fraxinifolia is native to the Caucasus and northern Iran, a wetland species that thrives on constantly moist soil, exactly the condition it gets growing at the edge of the artificial lake beside the Ponte delle Sirenette, a footbridge moved here in 1930 when the canal it originally crossed elsewhere in Milan was filled in. Its trunk measures 4.35 metres around and 18 metres high, and Italy's monumental tree registry lists it, along with a second specimen 1.6 kilometres away in the Giardini Montanelli, as the oldest Caucasian walnut in the city, though no source gives either tree an exact age or planting date. Compound leaves, similar in shape to an ash tree's, turn a warm gold in October and November alongside the marsh cypresses planted at the same waterline, briefly making the pond's edge the best autumn colour anywhere in the park. Visitors headed for the Castello Sforzesco or the Triennale rarely detour the extra hundred metres to the water's edge where it grows.

Il Noce del Caucaso dell'Orto Botanico di Brera
Caucasian Wingnut (Pterocarya fraxinifolia) · over 80 years, exact age undocumented · Brera
The famous trees in this garden are the two ginkgos of 1775, and neither of them is the one the state decided to protect. That honour went to a Caucasian wingnut at the back of the arboretum, declared a monumental tree of Italy on 11 February 2025, the first tree in the Orto Botanico di Brera ever to carry the designation, granted in the year the garden turned 250. Pterocarya fraxinifolia comes from the forests between the Black Sea and northern Iran, where it grows in ground too wet for most hardwoods, and it behaves in Milan the way it behaves at home: instead of one clean column it throws its limbs sideways into a low green dome, with a root system spreading as wide as the crown. The national register measures the trunk at 4.7 metres around and the tree at 29 metres, which makes it the tallest of the three wingnuts standing in central Milan and the only one on university ground. Its age has never been established by ring count or planting record; the university says over eighty years, which is a floor rather than a figure. In summer it hangs chains of winged green seeds half a metre long from every branch, the detail that gives the genus its name, from the Greek for wing and nut.

Il Platano della Biodiversita
London Plane (Platanus x acerifolia) · age undocumented, likely 100-180 years · Porta Venezia
Milan picked one plane tree in this park and started counting what lives on it. The city's monumental tree file calls it simply Platano VTA 43474, and it was entered into a research cycle measuring how much biodiversity a single urban tree carries in its crown and on its bark: the beetles, lichens, mosses, spiders and birds that treat 30 metres of plane tree as an address. The answer, in a city of 170,000 street and park trees, turns out to be a lot, which is why a tree with no legend attached to it now has a municipal page of its own. It stands about 30 metres tall on a trunk 1.6 metres thick, and its roots do something planes often do in compacted parkland: instead of diving, they spread flat across the surface of the root plate like poured wax. The city built a low wooden fence around the base purely to keep service vehicles off them. Its main limbs join the trunk at weak, narrow angles, so rather than shorten them, arborists tied them back to the trunk with anchoring cables. Almost nobody walking the path notices either the fence or the cables, which is the point of both.

Il Noce del Caucaso dei Giardini Montanelli
Caucasian Wingnut (Pterocarya fraxinifolia) · age undocumented, among the oldest of its species in Milan · Porta Venezia
Milan has three Caucasian wingnuts worth crossing town for, and this is the widest of them: 5.5 metres around, against 4.7 in the Brera botanical garden and 4.35 for the better-known specimen leaning over the pond in Parco Sempione. The city's own arborists pair this tree with the Sempione one as the two oldest of their species in Milan, which is as close to a date as anyone has put on either. It is a squat, wide, low tree rather than a tall one, 20 metres at most, because Pterocarya fraxinifolia spends its growth on width and on suckers: left alone it throws up new shoots from the base until a single tree reads as a thicket. Ash-like compound leaves, sometimes 60 centimetres long, turn butter yellow in late October. The species arrived in European gardens from the Caucasus and northern Iran in the early 1780s, brought back by a French botanist who found it growing in the wet forests south of the Caspian, and Milan planted it in parks for the same reason it planted bald cypress: land near ornamental water needed trees that would not sulk with wet feet. Walk the gardens' western edge toward Via Manin and it is the broad, many-stemmed one nobody photographs.

Il Platano del Giardino Bazlen
London Plane (Platanus x acerifolia) · age undocumented, likely 120-200 years · Porta Romana
The garden is named after the two men who invented Adelphi, and the tree is the only thing in it older than the publishing house. Roberto Bazlen and Luciano Foa founded Adelphi Edizioni in Milan in 1962; the small green square off Corso di Porta Romana that carries their names is mostly a children's playground now, and this plane is the last big tree left standing in it. Its top was cut out at some point, which took metres off its height and left it stockier than it should be, but the trunk is still 1.95 metres thick, wide enough that the whole playground arranges itself around the base. The city is blunt about what happens next. Wood-decaying fungi have colonised the trunk and cannot be removed, so the tree is inspected at the collar and at every branch join, and the municipal page states plainly that it will be kept for as long as its presence does not create a safety problem over the play area beneath it. That is an unusually honest sentence to publish about a monument, and it is the reason to go now rather than eventually. Planes tolerate Milan's air better than almost anything else, which is how this one outlasted every other large tree on its own block.

Il Platano Siamese di Villa Litta
London Plane (Platanus x acerifolia) · age undocumented, planted with the villa's 18th-century park · Affori, Municipio 9
Two plane trees grew close enough together here that they stopped being two. Their roots fused, then part of their trunks, then their crowns interlaced, and the result is catalogued by the city as one tree, Platano VTA 9595, nicknamed the Siamese. It reaches 34 metres, and the reason the city protects it has less to do with size than with occupancy. Colonies of ring-necked parakeets and starlings nest in its cavities, crows keep a nest in the crown, and until a few years ago the large hollow on the north trunk held a Great Grey Owl, a bird whose natural range is the boreal forest of Lapland and Siberia. Woodpeckers drill the trunk for the insect larvae that come with rotting heartwood, and those holes are also the clearest sign of what is happening inside: the city writes that the tree is at the end of its biological cycle, its internal decay advanced, its stability worse than it was, the heavy steel cables binding the two trunks together recently replaced. It stands 300 metres from the Pianta of Affori, in a park the Litta family laid out in the second half of the 1700s, and a visit is worth making sooner rather than later.

Il Platano di Piazza Sant'Ambrogio
London Plane (Platanus x acerifolia) · age undocumented, likely 100-180 years · Sant'Ambrogio
This plane tree joined Italy's national register of monumental trees in November 2025, which makes it one of the newest protected trees in the country and one of the taller ones in Milan. It stands 34 metres on a trunk 4.2 metres around, in the square in front of the Basilica di Sant'Ambrogio. Regione Lombardia announced it in a batch of 48 new entries that took the region's total to 476 recognised specimens.
Its age has never been published. Italy's national register carries girth and height and no field for years, and no city document or newspaper survey has filled the gap, so the only honest handle is size. A London Plane of this girth in Milan is usually somewhere in its second century, and the range given here is exactly that: an estimate read off a tape measure, not a record.
What it stands over is dated to the year. The basilica behind it was founded in 379 by Ambrose himself, and the low brick building with two unequal towers that you see today is the eleventh and twelfth-century replacement. Against that clock the tree is a newcomer. Against any other it is old.
It is also the tree most often photographed by accident in this city, sitting in the background of everybody's picture of the church, while being the reason the square has any shade at all.

Il Platano di Viale Cervantes
London Plane (Platanus x acerifolia) · age undocumented, likely 90-160 years · Sempione
Parco Sempione is the most walked park in Milan, and this tree only entered the national register of monumental trees in November 2025. It stands on Viale Cervantes at 33 metres, on a trunk 3.9 metres around, one of 48 Lombard trees designated in a single announcement that took the region past 476 protected specimens.
Its age is not on record. Italy's register lists girth and height and leaves the years blank, and no local survey has ever dated this one, so the two numbers on the tape are the only figures that describe it honestly: 390 centimetres around, 33 metres up. Everything past that is inference from size, and inference is the right word for it.
Where it stands is more interesting than what it measures. Viale Cervantes runs through the park between the Castello Sforzesco at one end and the Arco della Pace at the other, which makes it a route rather than a destination, and almost everyone on it is going somewhere else. The same avenue carries the Caucasian Wingnut that bends out low over the park's pond, close enough that the two are a single short walk. Between them they make this stretch the part of Sempione worth slowing down for, which is not how most people use it. It is 33 metres of reason to stop.

Il Platano dei 34 Metri ai Giardini Montanelli
London Plane (Platanus x acerifolia) · age undocumented, likely 110-190 years · Porta Venezia
Depending on which document you trust, this is either one of the two tallest trees in Milan or simply one of the taller ones. Il Giorno's survey of the city's monumental trees calls 34 metres the greatest height reached by any plant in Milan and names two plane trees that get there, one at Villa Litta and this one, off via Palestro. Italy's national register separately lists a Villa Litta plane at 43 metres. The title is contested, and that is worth saying rather than picking a side.
The measurement of this tree is not contested: 475 centimetres around the trunk, 34 metres tall. Its age is blank. The national register has no field for years and no newspaper or municipal file has dated it, so girth and height are the only honest numbers here.
It is also not the famous tree in these gardens. That is the plane with the 8.36-metre trunk, dated to 239 years, which grew outwards into five limbs instead of upwards. This one did the opposite. It has a second registered plane nearby at 32 metres, plus a bald cypress, a Mediterranean hackberry and a Caucasian wingnut: six register-listed monumental trees inside one set of railings, in a park first laid out in 1784.
Nobody stops for this one, because in company like that, being the tallest is not conspicuous. Look up rather than at the trunk.

The Archdevil of Villa Marietti Radice Fossati
Mediterranean Hackberry (Celtis australis) · Villapizzone
The comune's own page for this hackberry calls it arcidiavolo, the archdevil, after a folk tale that blamed its hooked leaves on Lucifer, said to have carried the species down from heaven clutched in his claws. The city's monumental-tree list is usually a good deal drier than that.
The tree stands in the park of Villa Marietti Radice Fossati, in Villapizzone, northwest of the centre. The villa was given its rural character by the Radice Fossati family, fell into disrepair through the 1970s, and was pulled back out of it by a small experimental community of Jesuit fathers. The Comune di Milano took ownership in 1993 and confirmed the community's loan of the buildings, which have been residential ever since. So the buildings are somebody's home and the park around them is not, and the city says plainly that with the discretion due to an inhabited place you may pass through the gate and visit the park.
The trunk measures 4.2 metres round and the crown spreads more than 20 metres, throwing shade over roughly 200 square metres by the comune's reckoning. Its roots, structure and vegetative state are all recorded as good, and nothing on record says the tree has ever needed work. Nobody has published an age for it, only that girth, among the largest for the species anywhere in Milan.

Il Platano di Viale Montesanto

A newspaper survey of Milan's monumental trees once put the city's ceiling at 34 metres. Italy's national register disagrees in several places, and this plane is one of them: 38 metres, growing at a street number rather than in a park.
It stands outside Viale Montesanto 4 to 6, on the ring of boulevards that traces the line of Milan's sixteenth-century Spanish walls, on the stretch between Porta Garibaldi and the Giardini Montanelli. The register gives the trunk at 5.25 metres round. The city's celebrated plane, the Platano di Indro in the Giardini Montanelli, carries 8.36 metres and spent it going sideways into five limbs. This one had a pavement, a road and a row of facades, so it went up.
Nobody has published an age for it. The national register carries girth and height and keeps no field for years, and no municipal file or local survey has filled the gap for this particular tree, so the tape measure is the only evidence there is. If you know when this stretch of the viale was planted, tell us and we will say so.

Il Platano di Piazzale Libia

Milan's best known plane trees stop at 34 metres. This one is 35, and it is standing in the middle of a traffic square.
Piazzale Libia lies about a kilometre out from Porta Romana in the south-east of the city, a junction broad enough to have kept room in the middle of it for a tree this size. Italy's national register of monumental trees lists the plane there at 35 metres on a trunk 4 metres round. That is taller than the register's own entry for the plane in front of the Basilica di Sant'Ambrogio and taller than the one in the Giardini Montanelli that a local survey named among the tallest plants in Milan.
Street planes almost never get the chance. Across Italy they are cut back on a cycle to clear the wires and the balconies, and a plane that has been topped does not come back to a height like this. Whatever else was done to this tree, nobody took its crown out.
Its age is not recorded anywhere. The national register measures girth and height and stops there, and no other document names this tree at all, so the years are simply missing. Anyone who knows when the square was planted can close that gap for us.
Nothing to pay and nothing to open. Cross at the lights, stand under it, and work out how much of the sky it is holding up.

The Plane of Viale Vittorio Veneto 3
London Plane (Platanus x acerifolia) · Porta Venezia / Bastioni
A story went round Milan in 2018 that the big plane on Viale Vittorio Veneto, growing in the old tram-line median near Porta Venezia, had dried out and been cut down. It probably wasn't this one. That felled tree measured about three metres round; this one, still standing at the same address, measures 5.70 metres, nearly double, too large a gap to be the same trunk misremembered. The register lists this plane as one of the largest in the city by girth, 36 metres tall.
Viale Vittorio Veneto runs along the Bastioni, the boulevard laid over Milan's old Spanish city walls after they came down, three hundred metres from the plane trees and monuments of the Giardini Indro Montanelli. No source beyond the register names this specific tree, so its age and any history particular to it stay unrecorded.
It grows as a street tree on the public boulevard, free to see at any hour, no gate and no ticket. If you know anything about its planting, or about the tree that really was felled here in 2018, tell us.

Il Platano Grande dei Giardini Montanelli
London Plane (Platanus x acerifolia) · age undocumented, likely 100 to 200 years · Porta Venezia
Milan's monumental-tree register calls this one simply the platano grande, the big plane, and at 6.25 metres round it is among the widest trunks the city has measured in any park. Lightning found it at some point and split part of its crown; rather than remove the damage, the city's arborists cabled the broken limbs back to the trunk, and the cables have held since. Woodpeckers moved into the wound the strike left behind, hollowing a nesting cavity into wood already opened by the burn, and researchers from Universita Bicocca have used the tree to study what actually lives in an urban canopy this size, cataloguing the insects and small fauna that treat 28 metres of storm-scarred plane as home. Someone once tried to saw into the trunk itself; the cut has healed over but is still readable if you know where to look. No source records when it was planted, so this is Ancient Trees' own honest estimate rather than a documented age: judged against two smaller, similarly dated planes elsewhere in the same garden, it is probably a century old at the least, maybe close to two. It stands inside Giardini Montanelli, a five-minute walk from the tree the city calls its own 'biodiversity plane', which makes this corner of the park worth slowing down for twice over.

I Platani di Villa Litta Modignani
London Plane (Platanus x acerifolia) · not documented · Affori, Municipio 9
Two plane trees stand twelve metres apart in Villa Litta Modignani park, and Italy's national monumental-tree register puts the larger at 43 metres, which would make it the tallest tree on this page by five metres. Read that carefully rather than as a settled fact: a differently dated citation of the same government dataset gives smaller figures for planes at this same park, and nothing independent of the original register has come along to referee between the two versions.
What both accounts agree on is that these are big trees. The register's own measurement puts the larger of the pair at 5.5 metres round, the smaller at 4.8 metres, either alone worth the detour. They stand about 150 metres from the park's own fused Siamese pair, two planes grown so close together their trunks merged into one, and 340 metres from La Pianta di Affori, the plane a persistent local story ties to Napoleon. Three separate plane-tree stories inside one Affori park.
Nobody has published when either tree was planted. Italy's monumental register has no age field for any entry it holds, a gap that runs through the whole dataset rather than this tree in particular, so treat the absence as the register's limit rather than a fact about the tree.
The park is free and open daily, an eight-minute walk from Affori's own metro stop.

London Plane (Platanus x acerifolia) · not documented · Affori, Municipio 9
This plane carries a name nobody has explained. Affori calls it la Pianta di Manzoni, the Manzoni plant, and the label is older than any of the data attached to it: a local contributor mapped that name onto this exact spot in 2011, nine years before anyone tagged the same point with the national register's measurements. The name is not a government label. It is what somebody in the neighbourhood already knew.
The obvious suspect is the villa. In the nineteenth century Villa Litta Modignani was Count Trivulzio's salon, and the intellectuals local histories name among its visitors include Alessandro Manzoni, who wrote I Promessi Sposi. Whether the novelist ever stood under this particular tree, or whether the name arrived some other way entirely, nobody has recorded. If you know the story, tell us.
What is on paper is thinner than the name suggests. Italy's monumental-tree register lists the tree at 28 metres tall and records no girth for it at all. The 4.1 metres round quoted here comes from a plaque beside the tree, copied down by a passer-by rather than a surveyor, so read it as a reading rather than a survey. There is no age anywhere: this register carries no age field for any tree it holds.
It is the third separately named plane in one small park, 65 metres from the fused Siamese pair and 150 from the taller two.

Il Bagolaro di Varedo
Mediterranean Hackberry (Celtis australis) · roughly 200 to 350 years, judged from a trunk 5 m round · Varedo, a day trip from Milan, not in Milan itself
Five metres round the trunk and twenty-seven metres tall, and it is only the largest of four. The national register lists four monumental hackberries in this one small park in Varedo, spread across about ninety metres: 500 centimetres of girth on this one, then 450, 390 and 350 on the others. Most Italian towns would be pleased with one.
They run along the edge of Parco 1 Maggio, the green between the town hall and the parish church, so the group works as a border rather than a set of specimens on a lawn. You walk along them instead of around them, and the biggest declares itself without anyone having to point.
Lombardy's regional tourism board singles out that largest trunk as measuring over five metres round and puts its diameter near 165 centimetres, where the national register's own figure works out closer to 159. Two measurements of the same tree, taken by different people on different days, and the difference is not worth arguing about.
The journey is a real day trip rather than a Milan stroll: the Milano-Asso line from Cadorna reaches Varedo in about twenty-five minutes, and the park is under ten minutes on foot from the station, free and open during park hours.
No age has been recorded for any of the four. If you know what dates them, tell us.

La Sofora di Varedo
Japanese Pagoda Tree (Styphnolobium japonicum) · Varedo, a day trip from Milan, not in Milan itself
Italy's national register of monumental trees rarely carries this species. The Sofora del Giappone at Varedo is a Japanese pagoda tree, an ornamental from East Asia, and it holds a register sheet of its own: 18 metres tall, with no girth recorded at all.
It stands on Piazza della Pace, the church square at the edge of the same park that holds the town's four monumental hackberries, about a hundred metres from the largest of them. Lombardy's regional tourism board reaches this tree first in its account of Varedo and calls it the interesting one before it gets to the giants. That is a fair order. The hackberries win on bulk; this is the one people stop in front of and fail to name.
What gives it away is the foliage, which reads like a robinia's, each leaf divided into small oval leaflets, and then the flowers, loose showy clusters of white to yellow, followed by pods that hang like beans. The pods are the family telling on itself: this is a legume, related to peas rather than to anything else on the square.
Nobody has put a tape around its trunk and nobody has dated it. The height is the only number anyone has written down. If you know either of the missing figures, tell us.

I Bagolari di Piazza Giovanni XXIII
Mediterranean Hackberry (Celtis australis) · roughly 150 to 300 years, judged from a trunk 3.9 m round · Pioltello, a day trip from Milan, not in Milan itself
Three trees on Italy's national monumental register stand on one ordinary town square in Pioltello. Two of them are these hackberries, a matched pair a few metres apart: 390 centimetres round and 22 metres tall, beside a companion of 350 centimetres and 20 metres. The third is a yew, a few steps further on.
The register lists the two hackberries separately and there is no sensible way to visit them separately. Somebody arriving at the piazza sees a pair, so that is how they are set down here, carrying the larger tree's figures, with the smaller one standing close enough that you cannot mistake which two are meant.
Piazza Giovanni XXIII is not a park or an estate garden. It is the square of a commuter town on the Martesana side of Milan, free, ungated, open at any hour, and the trees are simply standing in it. The local paper's survey of monumental trees in the Martesana names both hackberries and the yew at this address without measuring any of them. The numbers come from the register.
Getting there is honest work: fourteen minutes by train from Milano Centrale to Pioltello-Limito, then a walk of twenty to twenty-five minutes, which is longer than most stops on this map.
No age is recorded for either hackberry, and none has been estimated. If you know what dates them, tell us.

Il Tasso di Piazza Giovanni XXIII
European Yew (Taxus baccata) · Pioltello, a day trip from Milan, not in Milan itself
The smallest tree on this square is the one to be careful about. The yew on Piazza Giovanni XXIII measures 140 centimetres round and stands 10 metres tall, well under half the girth of the hackberries a few metres away, and it is on the national monumental register regardless.
Yews make a nonsense of judging a tree by its waistline. They grow slowly, and a modest trunk on a yew is not the evidence of youth it would be on a poplar. That is reputation rather than measurement, though, and nobody has done the arithmetic here: no growth rate has been applied to this trunk, no age has been derived from it, and guessing one would be worse than leaving the field empty.
What it has instead is company. The register puts this yew and two hackberries on one small piazza in a commuter town east of Milan, and the local paper's survey of monumental trees in the Martesana names all three at the same address, which is how the yew stops being an afterthought beside the bigger pair. Three registered trees within a few metres of each other make one stop rather than three, about twenty minutes on foot from Pioltello-Limito and fourteen minutes by train out of Milano Centrale.
Its age is recorded nowhere. If anyone has dated it, tell us.

Il Bagolaro di Villa Ghirlanda
Mediterranean Hackberry (Celtis australis) · over a century · Cinisello Balsamo, about 8 km north of central Milan
Ercole Silva wrote the book on English-style gardens in Italy, literally: his 1801 treatise Dell'arte dei giardini inglesi helped introduce the naturalistic parkland look to the country, and he tried the ideas first on his own land at Cinisello Balsamo, just north of Milan. This hackberry, its trunk 4.45 metres round and its crown 34 metres up, still stands in that garden.
The comune calls it bagolaro centenario, over a hundred years old, without giving a firmer figure, and marks it on the villa's own sensory-map trail as one of the garden's defining features alongside its obelisk. Celtis australis is native across the Mediterranean, and Milan knows the species as spaccasassi, the stone-splitter, for roots that push up paving stone; this one has had a century or more to test that reputation against the villa's own paths.
Villa Ghirlanda Silva's park is free and open daily, a fifteen-minute tram ride from central Milan rather than a walk: take the M5 metro to Bicocca, then tram 31 to the stop at the villa's own gate.
