What is the oldest tree in Haarlem?

Haarlem's age claims split along a clear line: the Lodewijk Napoleon Beech has an actual historical event pinned to it, a specific exiled king carving a specific mark in a specific two-year window, which is why it anchors this list as the oldest despite nobody having counted its rings. The other three candidates are honestly less certain. Haarlem's thickest tree, the Provinciehuis plane, has no recorded planting date at all; its size alone suggests a 19th-century origin, but that is inference from girth rather than a documented fact. The Kleverlaan cemetery's yew and Kenaupark's copper beech both belong to the Zocher family's 19th-century landscape schemes, laid out within a few decades of each other, and both are old enough to anchor their respective grounds without either source giving a precise age. None of that uncertainty is unusual for city trees planted before municipal record-keeping became routine; it simply means the crowned R carved into one beech's bark, however faded now, remains the single most specific piece of evidence this city's tree history has to offer.
