Qual é a árvore mais antiga de Assen?

Ages here come from the Landelijk Register Monumentale Bomen, which records a planting decade rather than a year, so every figure on this page is a band rather than a measurement. The register is the single source for nine of the ten, so those entries ship flagged rather than confirmed. The oak at Beilen carries a second source and a disputed age: 350 years locally, 1750 to 1800 by the register's own arithmetic. Three of the ten, the horse chestnut, the hollow oak and the broken cypress, stand together on Overcingel, a private estate landscaped in 1824 and free to walk with a card from Het Drentse Landschap's Assen office, or without one during the February and March crocus season. Two more, a weeping beech and a copper beech, share a pocket garden behind a house called Nieuw Echten, reached through a footpath between two front doors on Alteveerstraat. The rest stand on public ground: a deer park, a former manor's grounds now open as Valkenstijn, and a former hospital site along Beilerstraat. Where a pin is marked approximate, we know the site and not the exact trunk.
