Zwolle pulled down its fortifications and made a ring of parks out of the earth, which is why almost every old tree in the city is standing on a seventeenth century rampart. The best of them is a plane on the Potgietersingel: 33.6 metres tall with a trunk 719 centimetres round, which are measured figures rather than estimates. The oldest is a beech in the grounds of a small country house outside town, where Rhijnvis Feith, poet and mayor of Zwolle, spent his free time writing and in 1799 published an ode to the place in 34 verses.

London Plane (Platanus x acerifolia) · 175-225 years · Potgietersingel
Thirty three point six metres tall, and a trunk seven point one nine metres round. Those are measured numbers, not estimates, which makes this tree the most precisely known thing on this page and one of the largest planes in the Netherlands.
Seven metres of girth means roughly two and a quarter metres of diameter. Four adults with their arms out would not close a circle round it.
It is standing on a defensive earthwork. Zwolle's seventeenth century fortifications were demolished in the nineteenth, as they were in almost every Dutch town, and the earth was reshaped into a ring of singels and parks. So the ground here is made ground, thrown up to stop artillery and then handed to a garden designer, and this plane has had close to two centuries of deep, loose, undisturbed soil that no city street could offer it.
That is most of the explanation for the size. The other part is the species: planes tolerate everything a city can do to them, and given room they simply keep going.
Bark in flaking cream and olive plates, big maple-shaped leaves, and hard bristly seed balls hanging on their stalks all winter.
European Beech (Fagus sylvatica) · 225-275 years · Boschwijk
In 1799 the mayor of Zwolle published a 34 verse poem about this garden.
Rhijnvis Feith owned Boschwijk, a small country house not far outside the city, and he was one of the best known Dutch poets of his generation as well as a magistrate and mayor. He came out here in his free time specifically to write. 'Ode aan Boschwijk' is the result, and it is about this ground.
The beech is banded 1750 to 1800, which means it was somewhere between a sapling and a young tree while he was writing. It stands on the west side of the beukenloofgang, the beech avenue, which is the feature of the place: two rows planted close so the crowns meet overhead and make a green tunnel.
A beech avenue is a designed effect that takes a century to work and then works forever. It is also a slow-motion contest, because beeches planted that close spend their lives shading each other out, so the ones that survive are the ones that got up fastest.
Go in early May, when the new leaves are still translucent green and the tunnel glows rather than darkens.
Northern Red Oak (Quercus rubra) · 155-165 years · Boschwijk
It was planted for one week a year and it delivers.
Red oak is North American, it reached Europe in the seventeenth century, and it was planted across Dutch estates in the nineteenth for a single reason: nothing native here turns that colour. In late October a mature one goes deep scarlet and then rust, and it holds it for a fortnight while the beeches around it are doing their more restrained copper.
The leaves are the easy way to tell it from a native oak. They are much larger, with pointed lobes ending in tiny bristles, where a pedunculate oak has small soft rounded lobes and no bristles anywhere.
This one stands by the drive to number 7 on the west side of Boschwijk, banded 1860 to 1870, so it is a generation younger than the beech in the avenue and belongs to a later phase of planting on the same ground.
The acorns are worth a look too: squat and broad with a shallow saucer of a cup, quite unlike the neat long acorn of a native oak, and they take two years to ripen rather than one.
European Beech (Fagus sylvatica) · 155-165 years · Eekhout
The register calls these the poortbomen, the gate trees, which is a job description rather than a species.
Planting a pair of matched trees where a path enters a park is one of the oldest moves in the trade. It makes an entrance out of a gap, and it does it without a gate, a wall or a sign. You know you have arrived somewhere because two large trees have agreed to stand opposite each other. On the way out they frame the street.
This beech is one of that pair, banded 1860 to 1870, planted into the park that was made on the city's demolished fortifications.
Beech was the right choice for the role and a slightly cruel one. The species casts denser shade than any other large tree here, so a gate flanked by two of them is genuinely darker than the ground on either side, and stepping through is a change in light as well as in place. That is the effect, and it took a century and a half to mature.
The bark stays smooth and thin all its life, which is why a beech at a park entrance is always the one covered in carved initials.
Copper Beech (Fagus sylvatica f. purpurea) · 155-165 years · Van Nahuysplein
A dark tree next to moving water was somebody's decision.
This is a designed pairing and it still works: a copper beech placed to the left of a fountain on a square at the end of the Wilhelminasingel, planted between 1860 and 1870, when the ring of parks on the old fortifications was being finished and the city was arranging its new edges to be looked at.
Purple foliage was a strong colour to have available. Copper beech is a mutation of the common beech, propagated by grafting rather than seed, and in a nineteenth century planting scheme it functioned as the darkest tone on the palette, the thing you put where the composition needed something heavy. Against pale water and spray it does exactly what was intended.
A hundred and sixty years later it is also just a very large tree in the middle of a city, which is worth going to stand under. The canopy on a mature one is dense enough that the ground beneath stays dry in light rain.
In the last week of October it turns from purple to a deep burnt copper and the square changes colour with it.
Pedunculate Oak (Quercus robur) · 155-165 years · Kranenburg
It is in the new section, and it is a century and a half old, which tells you something about the scale a cemetery is planned on.
Burial grounds are the best places in a Dutch city to find big trees, and the reason is mechanical rather than sentimental. The ground is never redeveloped, never dug for services, never paved, never parked on, and nobody is in a hurry. A tree planted at the edge of a cemetery in the 1860s has had the single most stable century and a half available anywhere inside a growing city.
Oaks in particular are a standard choice for the setting, for the obvious reason that they outlast everybody in it several times over. Pedunculate oak routinely reaches four hundred years here, so this one is at roughly a third of its life.
It is easy to identify: acorns on long stalks, and leaves that sit almost directly on the twig with two small lobes clasping back around it.
Go in October. An oak this age in a good mast year covers the ground beneath it, and a quiet cemetery is one of the few places nobody sweeps them up.
Turkey Oak (Quercus cerris) · 100 years · Binnenstad
Zwolle's own list of special trees names exactly one Turkey oak in the whole city. This is it.
Everything else along the Menno van Coehoornsingel is what a Dutch town plants: limes, beeches, pedunculate oaks. Quercus cerris belongs to southern Europe and Asia Minor, which means somebody chose it deliberately, around 1920 to 1930 by the register's reckoning. The street carries the name of Menno van Coehoorn, the engineer who rebuilt the fortresses of the Dutch Republic against Louis XIV. His earthworks around Zwolle came down in the nineteenth century and the ground was handed to garden designers. This oak went in on that made ground, into a defensive ring that had already been converted into somewhere to walk.
The species gives itself away once you know the tells. Leaves cut into deep, irregular, sharply pointed lobes where the native oak is rounded, and buds sitting in a nest of long thin whiskers. The acorn cups wear the same whiskers, which is why the other name for the tree is the mossy-cupped oak.
The national register lists it as municipal property, protected for dendrological reasons rather than for size or age, which is an unusually honest entry: it is here because it is rare, not because it is enormous. A naturalist photographed and identified it in June 2026, so it is more than a line in a database.
Copper Beech (Fagus sylvatica f. purpurea) · 140 years · Groot Wezenland, edge of Assendorp
A fence went up beside this beech, and the tree has been taking it in ever since.
The national register says so in its own note: growing space here is tight, and sections of fence have grown into the trunk. That is less dramatic than it sounds and more inevitable. A tree lays a new layer of wood over its entire surface every year and cannot step sideways, so anything left leaning against it long enough ends up inside it. Give a beech a hundred and forty years and it will swallow railings, chains and signs without noticing.
The register puts the planting between 1880 and 1890, on private ground beside a housing complex just off the line of Zwolle's old canal ring. Copper beech was the strong colour of that period of Dutch planting, a mutation of the common beech that has to be grafted rather than grown from seed, and it went wherever a scheme needed its darkest tone. This one has held that job through two world wars and the rebuilding of the street around it.
Zwolle's own 2015 list of special trees records it as well, surveyed by a different office entirely: rode beuk, monumental, privately owned. Two registers, one tree, no argument between them.
What neither of them settles is how close a visitor can actually stand. If you have been, tell us.
Copper Beech (Fagus sylvatica f. purpurea) · 116-166 years · Binnenstad
The purple is a mask. A copper beech leaf is loaded with anthocyanin, which sits over the chlorophyll and hides it, so the green is still down there doing the work while the tree looks almost black from across the water.
This one stands on the Badhuiswal, a few steps from the bridge Zwolle calls the Stenen Pijp. Both bodies that have surveyed it call it monumental and municipal property, and both name the copper form rather than the plain beech. They differ only on the date. The national register bands the planting 1860 to 1870; the city's own 2024 list writes it as Fagus sylvatica Atropunicea and puts it at 1910. Same species, same status, same owner, so this is one tree recorded twice with fifty years of uncertainty attached to it. Call it somewhere between 115 and 165 years old and let a girth measurement decide later.
Either dating has it standing on this quay before the first cars came down it, and through the occupation and liberation of the city in the 1940s.
Come in the first half of May rather than midsummer. The new leaves open thin and translucent red, lit from behind, and hold that for a week or two before the pigment thickens and the whole crown settles into its usual near black purple.
London Plane (Platanus x acerifolia) · ~110 years · Wipstrik
The register says this plane was already standing when the tea house opened. The city's list says the tea house got here first.
Villa Urbana began serving on the Wipstrikkerallee in 1924, an inn and tea house on a long avenue leading out of Zwolle, and it is still a restaurant today under the name Loetje. The national register of monumental trees bands the plane beside it at 1910 to 1920, which puts the tree a few years ahead of the building. Zwolle's own 2024 list records the same species on the same street under the same private ownership and dates it to 1930, which puts it a few years behind. Everything else in the two entries lines up, so the tree is roughly a century old and only the order of arrival is unsettled.
Its condition is not in doubt, and the register is blunt about it: growth and vigour have diminished. This is a plane with a hundred years of roadside city life behind it and a crown that has thinned, rather than one in its prime.
Go for the pairing instead. It stands with a copper beech at a corner of the avenue where people have been sitting outside with a drink for a century.
Bald Cypress (Taxodium distichum) · 100 years · Wipstrik
Huis de Paddestoel means Toadstool House, and the bald cypress carrying its name stands where the paperwork about it does not quite agree with itself. The national register lists the tree's address as Herenweg 33, but its own coordinate sits nearly a kilometre away, at Herenweg 131 to 133 in the Wipstrik district, exactly where a 1991 photograph in a local historical archive identifies "Huize de Paddestoel van Schulte Nordholt". The municipality's 2015 survey of the city's protected trees lists only one Taxodium distichum on the entire street, also placed in Wipstrik, also municipally owned, which is almost certainly this same tree rather than a second one nobody else has recorded. Planted somewhere around 1920 to 1930, it now stands close to a century old on the public road verge, at what was once the edge of the private grounds around the house. Bald cypresses are unusual among conifers for dropping their needles every winter, turning a rust orange first, so the tree rewards two visits: one in leaf, one bare. The exact planting year has not been confirmed, so treat the century as an estimate rather than a measurement. The register itself calls the tree visible and open to the public, which the road verge it stands on bears out.
Silver Lime (Tilia tomentosa) · 120 years · Spoolde, Park 't Engelse Werk
Of the roughly two hundred trees Zwolle's council lists in Park 't Engelse Werk, one is a silver lime. The rest run to common limes and beeches by the dozen, which is what makes this one worth finding. Stand under it on a breezy day and the leaves flip to show their felted, silvery undersides, something none of its neighbours can do.
The national monumental tree register records a silver lime near the footbridge in the southern part of the park, planted between 1900 and 1910, which puts it at around 120 years old. The council's own list of special trees records a silver lime in the park planted in 1907. Since it is the only one on that list, it is very probably this tree, though the council gives no coordinate to prove it.
The park is much older than the lime. It was laid out between 1828 and 1830 in the English landscape style, probably by Hendrik van Lunteren, over the remains of 17th-century fortifications built on the advice of the military engineer Menno van Coehoorn. A brick tunnel from those works still survives in the grounds, and the whole park is now a national monument. It is Zwolle's oldest park and its busiest, running out to the Spoolderbos.
Nobody has published a girth or height for this tree yet. If you pass it with a tape measure, tell us what you find.
European Beech (Fagus sylvatica) · 130 years · Spoolde, Park 't Engelse Werk
In a park where beeches were planted in almost every decade from the 1870s to the 1930s, the national monumental tree register picked this one. Zwolle's own list of special trees records beeches going into Park 't Engelse Werk in 1877, 1887, 1907, 1920, 1927 and 1930, among other years. The register singles out the beech standing east of the restaurant, planted between 1890 and 1900, which makes it around 130 years old and the oldest of the three register trees in this part of the park.
Be clear about what that rests on. The register is the only source that names this particular tree. The council's list confirms that beeches of this age stand in the park, but it gives no locations, so it cannot say which is which.
The landmark it is named after has a longer story. The park has had a refreshment house near the dike since the 19th century, and it is very likely the same place the register means by the restaurant, though no source joins the two by name. When this beech went in, the park was already more than sixty years old: it was laid out between 1828 and 1830 in the English landscape style, and the big pond with its wooded islets had been added after 1874.
Nobody has published a girth or height for it. If you measure it, tell us, and help settle how it compares with its neighbours.
Copper Beech (Fagus sylvatica f. purpurea) · 120 years · Spoolde, Park 't Engelse Werk
A copper beech planted at the water's edge around the time the 20th century began, and still standing there: that is what the national monumental tree register records in the southern part of Park 't Engelse Werk. Its entry, filed under the Dutch name bruine beuk, gives a planting band of 1900 to 1910, which puts the tree at around 120 years old. That age is read from the band rather than from a record of the day it went in.
The water it stands beside is itself an addition. The park was laid out in 1828 to 1830 on the site of old fortifications, and the large pond with its wooded islets came later, after 1874. So the beech was planted into a landscape that had already been reshaped once.
Zwolle's council keeps its own list of special trees, and it records several copper beeches in this park, planted in 1887, 1927 and 1937 among other years. That confirms copper beeches of this generation grow here, but the list carries no locations, so it cannot tell us which entry is this tree. The register alone names this specimen, and we say so plainly.
What you get on the ground is a small cluster: the park's silver lime stands about 45 metres away, and the register's beech by the restaurant about 200 metres off. Nobody has published a girth for this one. If you have a tape measure, send us the number.
Weeping Beech (Fagus sylvatica 'Pendula') · 120 years · Boschwijk
The garden around this weeping beech was designed by a poet who was also the mayor of Zwolle. Rhijnvis Feith owned the Boschwijk estate and, after 1783, laid out its landscape garden on the southeast side of the house in the English style, with winding paths and water. The beech came more than a century after him. The national monumental tree register gives it a planting band of 1900 to 1910, which makes it around 120 years old, an age read from that band rather than from any planting record.
What stands there now is a weeping beech in the lawn, the kind of tree whose branches hang down towards the grass rather than reaching out. The register says little more: its history field for this tree is blank. The national monument listing for Boschwijk's historic garden confirms the design, the protection and the public park, but does not mention this beech by name. So the tree rests on the register's word alone, and we flag it as such.
It is worth combining with two other register trees in the same park that are already on this map, the beech of the Boschwijk avenue and the red oak, which stands about 150 metres from here. Together they make a short loop through Feith's garden.
Nobody has published a girth or height for it. If you visit, a measurement sent to us would fill the gap.
