Zaanstad is seven Zaan villages fused into one municipality, powered for three centuries by more windmills than anywhere in Europe, grinding paint, oil and timber long before factories existed elsewhere. Its three verified trees are scattered across that history rather than gathered in one park: a disputed-age copper beech in a Zaandam cemetery, a plane that has outlived the industrial waterfront beside it, and an ailing horse chestnut in Westzaan. All three rest on a single register, honestly flagged as single-sourced.

Copper Beech (Fagus sylvatica f. purpurea) · 140 years · Zaandam
This tree's own file cannot agree with itself about its age. The register's planting band puts it in the 1880s, while the note underneath says the cemetery dates from the early twentieth century and that the copper beech was planted when the cemetery was. Nobody has reconciled the two, so the age here is a range rather than a date, and the later reading would make it younger still.
What is not in doubt is that it was planted as one of a set. The register reckons there were once several copper beeches along the avenues of this burial ground, and five of them still stand further east, listed under a number of their own. This one has the middle of the ground to itself.
A copper beech is a colour mutation of the ordinary green beech. The purple pigment masks the chlorophyll underneath, so the dark form grows a shade less vigorously than a green one and rarely wins a fight in a wood. Nurseries propagate the good ones by grafting, because seedlings are a lottery. Which is to say that almost every large copper beech you meet is somewhere a person decided to put one, and a cemetery avenue was exactly that kind of decision.
You will find it in the middle of the burial ground off the Zuiddijk in Zaandam, open in daylight. Only the national register describes this tree.
London Plane (Platanus x acerifolia) · 120 years · Zaandam
A plane tree handles dirty air by taking its skin off. The bark comes away in irregular plates, carrying the year's soot and grime with it, which leaves the trunk mottled in olive, cream and grey and is the reason this species ended up lining the streets of every industrial city in Europe.
Zaandam was a good place to need that trick. The Zaan district ran first on wind and then on coal: hundreds of mills sawing timber, crushing seed for oil and grinding pigment for paint, and after them the cocoa and biscuit works whose smell still carries across the town on the right wind. The register puts this plane's planting between 1900 and 1910, which sets it down in the middle of all that.
Everything around it has since changed. The register's note on the tree is really a note about its neighbours: the Zaan bank is under heavy development, and this early twentieth-century plane has outlasted those developments for well over a century now. The mills, the wharves and most of what it was planted beside have gone.
Planes are hybrids, oriental plane crossed with American sycamore, and in city terms they are close to indestructible. Cut back to stumps they come again, which is precisely why councils keep planting them. This one stands on the public square at the Westzijde; the pin marks the square rather than the trunk itself.
Horse Chestnut (Aesculus hippocastanum) · 100 years · Westzaan
A fungus at the foot of a tree is the last thing to appear, not the first. By the time brackets are showing at the base, the organism has usually been working through the roots and the butt of the trunk for years, and what you can see is only its fruit.
That is roughly the story the register tells here. After a century of standing quietly in the green strip of the Kerkbuurt, this horse chestnut has gone downhill sharply in the last few years, and the inspectors think the heavy fungal growth at its base is the likely reason. They are careful about it: possibly, they write, not certainly.
They put the planting at around 1925, which makes the timing tidy to the point of being irritating. It is faltering at almost exactly a hundred. A horse chestnut does not read as an ancient tree at that age, but a hundred years is a long working life for one standing in a village verge.
Westzaan is a ribbon village strung along a single old road, and the Kerkbuurt is its church quarter. Nothing in the register says this tree is coming down, but one in that condition is worth going to see sooner rather than later. It still flowers white in May and it still drops conkers in autumn.
The national register is the only source that describes it, so if you know its history, tell us.
