The Koekamp Oak

William of Orange personally guaranteed this oak's forest would survive forever, four and a half centuries before anyone thought to count the tree's actual rings. In 1576, with the Eighty Years' War against Spain already underway, Orange signed a deed on behalf of the States of Holland promising that the Haagse Bos and the Koekamp within it would never be sold or logged for timber, a rare 16th-century conservation guarantee that has, remarkably, held. This oak, standing roughly 300 years old inside the Koekamp's fenced deer enclosure, is a direct beneficiary: too young to have existed when Orange made his promise, but growing on land that promise had already protected for well over a century by the time this acorn took root. Red and fallow deer still graze around its base today, the same enclosure function the Koekamp has served for centuries, a working piece of countryside preserved inside a European capital rather than a themed park built to imitate one. The forest's luck ran out only once, briefly: during the German occupation, half of it was felled for military purposes, a rare interruption in an otherwise unbroken run of protection stretching back to a promise a Dutch prince made before his own war was won.
