Geneva's oldest trees mostly arrived as souvenirs. Diplomats, bankers and returning travellers filled the city's 19th-century lakeside estates with cedars from Lebanon, sequoias from California and planes grown wild before the gardens around them existed, imports that outlived the households who planted them and now stand in parks the city inherited along with the trees. One tradition runs even older: an unbroken 208-year civic ritual of watching a single chestnut tree for the first leaf of spring, Switzerland's oldest recorded natural-history dataset.

The Official Chestnut Tree
Horse Chestnut (Aesculus hippocastanum) · about 11 years (the tradition dates to 1818) · Vieille-Ville
Geneva has kept an unbroken written record of a chestnut tree's first spring leaf since 1818, one of the oldest continuous phenology datasets anywhere, third-oldest in the world by the canton's own claim. Every year the sautier, the secretary of Geneva's cantonal parliament, walks to a designated tree on the Promenade de la Treille, checks for the season's first open leaf, and reports the date to the press, a civic tradition treated with the same seriousness as a budget vote. The tree doing the job today is the fourth in the role. The first died young; the second lasted from 1905 to 1929; the third served for 86 years before a root fungus called armillaria killed it from the inside, its final recorded observation logged on 13 March 2015. Its replacement was chosen that September for one quality above all others: standing conveniently opposite Tour Baudet, the tower housing the cantonal government, so the sautier's walk stays short. This is the youngest tree on this list by a wide margin, but the record it now carries is the oldest thing about it, two centuries of Geneva watching the same small square for the first sign spring has actually arrived.

The Cedars of Parc Beaulieu
Cedar of Lebanon (Cedrus libani) · about 290 years · Grottes-Saint-Gervais
A French naturalist smuggled cedar seeds out of a garden in England, sowed them at the Jardin des Plantes in Paris, and a handful of the resulting saplings ended up gifted to a Genevan baron in 1735. Bernard de Jussieu's seed run is the same one behind the celebrated Cedar of Jussieu still standing in Paris today, a rare case of two cities' oldest cedars sharing one 18th-century courier. Baron Jean-Francois de Sellon planted his share at his lakeside estate, now Parc Beaulieu, and two of the resulting trees still stand there, close enough together to read as one destination rather than two. Geneva's own tree register calls them the oldest cedars of Lebanon in Switzerland, and possibly in Europe, a claim this entry repeats as the city's own rather than an independently verified fact. Lightning has since taken several metres off the tallest, now 27 metres instead of the 30-plus it once reached, and its trunk has grown past 6 metres around, canopy spread 34 metres, numbers that make the loss of a treetop look almost incidental. Napoleon is said to have visited the estate in 1800, back when the cedars were already mature enough to be worth the detour.

The Grange Cedar
Cedar of Lebanon (Cedrus libani) · 200-225 years · Eaux-Vives
This cedar is a direct descendant of the Beaulieu cedars across town, grown from their seed once the Lullin family decided their own lakeside estate needed the same fashionable tree everyone else was planting. Cedars of Lebanon became the must-have addition to Geneva's English-style landscaped parks from around 1800 onward, and the Grange estate, later the city's largest park, got its own sometime in that same window, though no source pins the planting to an exact year. Two centuries on, the tree has outgrown its parent generation: 7.62 metres around the trunk and just over 25 metres tall by a 2019 measurement, a girth that would take four or five adults joining hands to encircle. Parc La Grange has a literary footnote worth knowing: Franz Liszt and Marie d'Agoult stayed at the estate in the 1830s, and their daughter Cosima, later Richard Wagner's wife, was born nearby during that same visit. The cedar would already have been a substantial young tree by then, decades into growing toward the giant it is now. It stands near the park's main house, an easy stop on a walk through Geneva's rose garden and lakeside paths.

The Botanical Garden Plane Trees
London Plane (Platanus x acerifolia) · at least 298 years · Nations
Five plane trees in Geneva's botanical garden were already mature enough to appear on a cantonal cadastral map in 1728, nearly two centuries before the garden itself moved onto the land they stand on. The Conservatoire et Jardin botaniques relocated here from Parc des Bastions in 1905, onto the former Ariana estate that property heir Gustave Revilliod had left to the city, and inherited these five trees as a ready-made avenue rather than planting anything itself. City gardeners since have deliberately left them alone: unlike Geneva's street plane trees, pruned hard every winter into tight pollarded shapes, the botanical garden's five were allowed to spread their branches naturally, the difference between a tree kept small for a pavement and one left to become what a 300-year-old plane actually looks like. Botanists have reclassified them more than once; they currently go by Platanus x hispanica, having previously been labelled Platanus x acerifolia, the taxonomy shifting even as the trees themselves have not changed in decades. The central avenue they form is still the garden's spine, a shaded walk near the entrance from chemin de l'Impératrice, in the Nations district a short tram ride from the city centre.

The Sequoia Grove of Parc Barton
Giant Sequoia (Sequoiadendron giganteum) · 150-170 years · Pâquis
About thirty giant sequoias grow in one Geneva park because a British diplomat's family fell for a California fashion, and because his daughter later made sure nobody could ever cut them down. Robert Peel, son of the British prime minister and Britain's own representative to Switzerland, bought the Barton estate in 1858, right as giant sequoia seedlings from the American west were becoming the trophy planting for European estate owners with money and an English-style park to fill. He planted a grove instead of a single specimen, and it grew into what the city now calls a cathédrale végétale, a vegetative cathedral, dense enough to change the light underneath it. His daughter, Alexandra Barton Peel, inherited the estate and grew as attached to its trees as her father had been. When she bequeathed the property to the Swiss Confederation in 1935, she attached one condition, that it never be divided and that the trees growing there never be felled. The estate came close to a very different fate: League of Nations planners considered Barton as a site for their new headquarters after 1919, and only Barton Peel's refusal to sell kept the grove intact for what it is today, a public park a short walk from the lakefront.

The Place du Cirque Plane
London Plane (Platanus x acerifolia) · about 120 years · Plainpalais
The largest plane tree in downtown Geneva grows in the middle of one of its busiest intersections, and the reason it got that big is buried under the pavement. Place du Cirque sits on the former bed of the Arve river, rerouted decades before the tree was planted around 1900, and the water table left behind still runs close enough to the surface for the tree's roots to draw on it freely. The result, after roughly a century and a quarter: 35 metres tall, a trunk 4.25 metres around, one and a half metres in diameter, dimensions that would be remarkable in a forest and are startling in the middle of a traffic circle. Thousands of pedestrians pass directly under its canopy every day without necessarily registering that they are walking beneath one of the biggest trees in the canton, let alone the largest one standing in the city centre itself. The square takes its name from the travelling circuses that once pitched their tents on this stretch of the Plainpalais plain. The tree arrived after most of that history, but has since outlasted every circus that has come and gone since.

The Venerable Oak of the Botanical Garden
Pedunculate Oak (Quercus robur) · roughly 300 years · Sécheron
The city has drawn a quiet zone around this oak to keep visitors' feet off its roots. The périmètre de tranquillité exists because soil compaction is what kills old trees in busy gardens long before age does. Geneva's cantonal inventory rates this one's vitality as poor and its stage as senescent, which is less a death notice than the reason the perimeter is there at all.
It has earned the trouble. The City of Geneva's own museum trail names this exact tree and cites an inventory number that matches the register's, digit for digit, which is about as close to a positive identification as a tree gets. The trail dates it to 1719. That makes it roughly three centuries old, the elder of the botanical garden's living collection, and 710 centimetres round the trunk.
The same account says it once stood beside a Roman road that crossed this ground long before anything botanical did. The Conservatoire et Jardin botaniques only moved here in 1905, so the oak had been growing for 186 years before the garden arrived around it, and it is still the oldest thing inside the fence.
The 1719 date comes from that trail article rather than from a ring count or an archive entry, so treat it as a good estimate rather than a birth certificate. The Avenue de la Paix gate is the nearest way in.

The Naville Cedar
Cedar of Lebanon (Cedrus libani) · about 206 years · Eaux-Vives
A mayor planted this cedar in the summer of 1820 because his son had just been born. Jean-Edouard Naville was mayor of Eaux-Vives, then still a commune in its own right rather than a district of Geneva, and he put the tree into the ground on his Montchoisy estate to mark the arrival of Emile. Two centuries later the boy is long gone and the tree is 722 centimetres round.
Where it ended up is the other half of the story. The Route de Frontenex now runs past it, the address is simply opposite number 53, and the ground around it is road and building rather than lawn. Tribune de Genève, surveying the trees that tell Geneva's history, found it holding up well in the middle of all that concrete, and the cantonal register agrees: vitality good, development stage senescent, an old tree still doing its job rather than a failing one.
The 1820 date is unusually solid for a tree this age. Registers here often record a planting as the first of January, which is a filing habit rather than a record, but this one is backed by a named man, a named son and a stated season. It is a birthday present that outlived everyone at the party, standing at a kerb on a busy road out of town.

The Bald Cypress of Parc des Eaux-Vives
Bald Cypress (Taxodium distichum) · roughly 100-150 years · Eaux-Vives
Geneva's own lakeside walking guide files this tree under arbres insolites, unusual trees, and it earns the label every November by doing what no conifer is supposed to do. The bald cypress drops its needles. They go rust and copper first, the whole tree turning the colour of a beech, and then the branches stand bare all winter while the cedars around them stay green.
Taxodium distichum comes from the swamp forests of the American southeast, where it grows with its feet in standing water and pushes woody knees up through the mud around the trunk. This one has drier ground and the lake a few metres off, a trunk 330 centimetres round, and a vitality rating of excellent, the top grade the register hands out.
Nobody has dated it. The register carries a planting year of 1912, but that date falls on the first of January along with 21 other entries in the same file, which makes it an administrative default rather than a record. Judged on girth alone the tree is somewhere between one and one and a half centuries old, and that band is as tight as the evidence honestly allows.
It stands on the city's signposted route between Parc La Grange and Parc des Eaux-Vives, which strings this and twenty other named trees into a single walk along the water.

The Great Cedar of Port-Noir
Cedar of Lebanon (Cedrus libani) · roughly 200 years · Eaux-Vives
This cedar's age was worked out by measuring a different cedar. Nobody wrote down when it was planted, the cantonal register's date of 1850 falls on a first of January and is therefore a filing convention rather than a record, and no article or archive found so far names the tree at all. So the estimate borrows from the Naville Cedar on the Route de Frontenex, about a kilometre away: same species, same lake, same climate, and a documented planting in 1820. That tree has put on 722 centimetres of girth in 206 years, roughly three and a half centimetres a year. Apply the rate here, to 743 centimetres, and you get about two centuries, which is why the range on this page runs from 180 to 230 years instead of landing on a date.
The tree itself needs no arithmetic to be worth the walk. Forty metres tall, more than seven metres round, in good health, standing at the Port-Noir end of Parc des Eaux-Vives where the park runs out towards the water. A second, slightly smaller cedar stands about fifty metres off through the trees, near enough to see from here and far enough to be a different stop.
One register entry, one line of measurements and a growth rate borrowed from a neighbour. A reader with a tape measure, or an archive card with a date on it, would improve on all of it.

The Tulip Tree of Parc de l'Impératrice
Tulip Tree (Liriodendron tulipifera) · roughly 100-150 years · Chambésy
The château at the top of this lawn is Italy's mission to the United Nations. The lawn is not: Geneva bought the estate in 1983 and kept the grounds public, so the terrace, the long view down it and the tulip tree standing at its head belong to anyone who walks up.
The city's own description of the park puts the tulipier de Virginie and a giant sequoia together at the top of that slope, and the tulip tree is the one worth the climb. Five metres and six centimetres round the trunk, a metre and a half through, grown in open ground with nothing crowding it, which is why it has the shape a Liriodendron is supposed to have and rarely gets in a city. The species is North American and takes its name from the greenish orange flowers it opens in June, high in the crown and easy to walk under without noticing. The leaves give it away instead, cut off square at the tip as though someone had trimmed them with scissors.
Its age is a girth estimate rather than a date. The register's planting year for this entry is one of the file's placeholders, so the honest reading is somewhere between one and one and a half centuries, on a species that grows fast when it is given room. Geneva's own page calls the park's trees centenarian and leaves it there too.

The Sécheron Plane
London Plane (Platanus x acerifolia) · roughly 150-200 years · Sécheron
Thirty-eight metres of plane tree stands in a green space off the Avenue de France, and the harder question is which green space. The avenue borders several in Sécheron, Mon Repos and the Perle du Lac among them, and nothing found so far names the ground this trunk actually stands on. The coordinates are exact. Only the name of the park is missing.
The tree is not in doubt. The cantonal register gives it 636 centimetres of girth, 38 metres of height and a crown spreading 33 metres, in good health. For scale, the plane in the middle of Place du Cirque, the largest in the city centre, measures 425 centimetres. This one is half as thick again and taller, and almost nobody writes about it.
Nor does anyone date it. The register's planting field is simply empty, so the age here comes from comparing girths with that Place du Cirque tree, which is about 120 years old and the same species on the same soil. That puts this one somewhere between 150 and 200 years, a band wide enough to be honest and narrow enough to be useful.
It sits a short walk from Gare Cornavin and the Sécheron rail stop, which makes it the easiest of Geneva's giants to reach without planning anything at all.

The Service Tree of Chambésy
Service Tree (Sorbus domestica) · about 60 years · Chambésy
Sorbus domestica is rare enough in Switzerland that a healthy one beside a road counts as a find. The service tree is the overlooked member of a familiar family, a relative of the rowan that grows into a proper timber tree and carries small brown fruit shaped like miniature apples or pears. Those fruits are why anybody ever planted it. Hard and sour straight off the branch, they were left to go soft and brown before eating, and went into cider and perry across southern Europe to sharpen them.
This one went into the ground in April 1966 on the Route de Pregny, which makes it about sixty years old, young for a tree on this list. The date is worth trusting for an unglamorous reason: the register records a real month for it, where its uncertain entries all default to the first of January. It measures 247 centimetres round and is in good health, and it is here for what it is rather than for how big it is.
The register is also the only source that mentions it, which is thin for a species this easy to mistake for a rowan or a wild service tree. If you know this tree, or know who put it there, tell us. It is a five-minute walk from the tulip tree in Parc de l'Impératrice, which makes the two of them one stop rather than two.

The Stone Pine of Parc des Eaux-Vives
Stone Pine (Pinus pinea) · Eaux-Vives
A Mediterranean umbrella pine has no obvious business on Lake Geneva, and this one is thriving. Pinus pinea is the tree of the Roman roadside and the Italian coast, a bare trunk running up to a flat parasol of a crown, and the silhouette reads as out of place among the cedars and planes of the Eaux-Vives parks. It stands 19 metres tall with a crown 17 metres across and a trunk 280 centimetres round, and the cantonal register rates its vitality as excellent.
The species is the source of pine nuts, which take three years to ripen inside cones heavy enough to be worth watching out for underneath. Whether this tree bothers producing them this far north is a fair question, and not one the register answers.
Nobody has dated it. The planting field for this entry is empty, not even carrying the placeholder January date that fills so much of the file, and no growth figure for stone pines in this climate turned up that would support an honest estimate. So the age here is blank rather than guessed. If you know when it went in, or know somebody at the parks department who does, tell us and it goes on the page.
It stands about 65 metres from the bald cypress, which makes the two of them a single short detour off the lakeside path.

The Plane of the University Garden
London Plane (Platanus x acerifolia) · at least about 150 years · Bastions
This plane did not grow here. A plaque at its foot records that it was transplanted from the Place des Alpes to the Promenade des Bastions in 1878, and a tree big enough to be worth moving was already a tree when it made the trip. So 1878 is a floor for its age rather than a birthday. How much older it is, nobody has established, and the canton's register carries no planting date at all.
What it moved into was the best address in Geneva for a specimen tree. The Bastions served as the city's botanical garden from 1817 until 1904, so a plane arriving in 1878 was being placed by people whose profession was placing plants. The collection later left for the lakeside. The tree stayed, and has outgrown everything the garden left behind.
It now measures 5.38 metres around and 31 metres tall, under a crown 38 metres across, wider than the tree is high, which is what a plane does when nothing crowds it for a century and a half. The canton's inventory files its development stage as senescent. It stands alone facing the entrance on the university garden side, inside a ring of barriers whose purpose is to stop students chaining bicycles to it, and Geneva's city arborist describes it as looking rather like the king of the courtyard.

The Hackberries of Place de l'Université
Mediterranean Hackberry (Celtis australis) · roughly a century old · Bastions
A fungus is eating these three from the inside, and the city said so itself. In 2020 Geneva's arborist told the Tribune de Genève that the micocouliers de Provence on the Place de l'Université are being hollowed out and risk coming down, which is a candid thing for a municipality to volunteer about trees it has listed as remarkable. The canton's inventory then recorded good vitality at its last field visit in 2024. Both readings can be true of a hollowing tree, which is why these are watched rather than felled.
There are three of them, standing together facing the entrance of Uni Bastions, close enough to read as one destination and collected here as one; the pin marks the group rather than a particular trunk. At this spot the register measures 3.3 metres of girth and 18 metres of height. They went in during the early 20th century, and the exact year is not recoverable from the record.
Mediterranean hackberry is a southern species living at the cool edge of its range in Geneva, which is part of why a set of them at this size is worth the canton's attention. In Provence its wood was the standard material for pitchforks, whip handles and walking sticks, chosen because it bends a long way before it breaks. These three have shaded a century of students crossing the square, and are now being tested from the inside instead.

The Oriental Plane of Domaine de Penthes
Oriental Plane (Platanus orientalis) · roughly 120 years · Pregny-Chambesy
Geneva has plane trees along half its streets and almost none of the tree they came from. The London plane that lines European cities is a hybrid, and this is the parent that gave it its name and most of its looks: Platanus orientalis, which the city's arborist calls a rare specimen on Genevan soil. It is also the tree the Tribune de Genève picked to open its walking tour of the canton's remarkable trees, which tells you where the professionals would start.
It stands in the garden of the Château de Penthes above the lake, 5.59 metres around and 20 metres tall, carrying a crown 25 metres wide. The canton's inventory rates its vitality excellent, which is not a given at that size. An arborist puts it at around 120 years and thinks the château's owners planted it, but that is his estimate rather than a record, he gave it in 2020, and no document naming the planting has turned up.
The grounds are nine hectares, free to walk, and kept by the gardeners of the city's botanical garden. The museum inside the château closed in 2022 when its foundation went bankrupt, and the garden simply carried on without it. Elsewhere on the lawn stands the stump of a giant sequoia that lightning finished in 1993, another of the estate's imported trophies. The plane has had better luck.

The Holm Oak of Cimetière des Rois
Holm Oak (Quercus ilex) · roughly 60 to 80 years · Plainpalais
This oak is nearly twice as wide as it is tall. Twelve metres of height, a crown twenty metres across, a trunk 2.64 metres round, and it sits at the main entrance of the Cimetière des Rois, the plot Geneva keeps for the people it wants to remember. Everyone going in or coming out passes under it.
Holm oak is a Mediterranean evergreen and has no obvious business this far north, yet the canton lists two of them as remarkable trees, this one and another in Parc Geisendorf, and the city's arborist rates the pair as equals. Being evergreen it looks the same in February as in July, which at a cemetery gate is closer to a job than a habit.
Behind it lies Jorge Luis Borges, who chose Geneva over Buenos Aires for the end and got a headstone carved with Old English, and somewhere behind it lies John Calvin, who asked in 1564 to be buried without a marker and was obeyed so completely that the stone bearing his initials marks a guess at the spot rather than the spot. A cemetery full of certainties about who is there and vagueness about exactly where.
The canton's last recorded field visit, in 2012, put the tree in good condition. Its planting is filed only as mid twentieth century, no closer. Which makes this a young tree keeping very old company.

The Himalayan Cedar of Parc Mon Repos
Himalayan Cedar (Cedrus deodara) · Secheron
A second giant grows a stone's throw from the Secheron Plane, and this one is a conifer rather than a plane: a Himalayan cedar, native to the high valleys of Kashmir and Nepal, brought to Europe's parks in the nineteenth century as one of the era's fashionable new conifers. Geneva's cantonal register puts it at 4.18 metres round the trunk, 28 metres tall and a crown spanning 23 metres, and rates its health good on a 2024 field visit, the freshest survey of any tree on this list.
Like its neighbour the plane, this cedar's exact park is not pinned down by any source found so far. The coordinates are precise, the green space off Avenue de France is not named with certainty (Secheron, Mon Repos and the Perle du Lac all border the same avenue), and the two trees stand close enough, about ninety metres apart, that a single stop covers both without walking anywhere else. The register carries no planting date, so this cedar's age is simply unknown rather than estimated. What is measured is measured well: a girth that would take three adults to encircle, on a species that can live for centuries in the right conditions. The nearest way in is the same one that reaches the plane, a short walk from Gare Cornavin or the Secheron rail stop.

The Himalayan Cedar of the Botanical Garden
Himalayan Cedar (Cedrus deodara) · roughly 114 years, planted in 1912 · Secheron
This cedar's growth and the garden's own site are almost exactly the same age. The Conservatoire et Jardin botaniques moved to its present Avenue de la Paix grounds in 1904 under director John Briquet, with the winter garden and surrounding landscaping built out over the following years; the cantonal register separately dates this Himalayan cedar's planting to 1912, a genuine recorded year rather than a placeholder, squarely inside that same building-out window.
It has grown into one of the garden's largest specimens: five metres round the trunk, 34 metres tall, a crown spreading 25 metres, most recently surveyed in August 2025 in good health. That makes it roughly a century old, younger than the garden's own oak nearby, which predates the garden itself by close to two centuries, but old enough to have stood through both world wars and the whole of the garden's modern development.
A second, slightly smaller Himalayan cedar from the same 1912 planting stands about two hundred metres away, last surveyed over a decade ago; this is the fresher and larger of the pair. Enter from Avenue de la Paix and the tree stands a short walk from the gate.

The Atlas Cedar of Parc La Grange
Atlas Cedar (Cedrus atlantica) · Eaux-Vives
Parc La Grange keeps two enormous cedars from two different mountain ranges. One, near the main house, is a Cedar of Lebanon descended from seed gifted in 1735. The other, over five and a half metres round the trunk, is an Atlas cedar, native not to the Levant but to the Atlas Mountains of Morocco and Algeria, and Geneva's cantonal register rates it in good health with a canopy 23 metres across and a height of 29 metres.
Cedar of Lebanon and Atlas cedar look similar enough at a glance, both broad and flat topped with the same grey green needles, that telling them apart takes a second look at the cones rather than a first glance at the silhouette. This one has no documented planting date, and the register's last field visit was in 2014, over a decade old now, the oldest confirmed sighting of any tree on this list. It is still a genuinely large specimen in a park built around genuinely large trees, worth remembering as a second cedar rather than a repeat of the one most visitors are pointed toward. This one stands elsewhere in the same grounds, near Avenue Alice-et-William-Favre, roughly fifteen minutes from the city centre by bus or tram.
