Roughly 1,500 to 2,000 years old.
Copenhagen's remarkable trees come with tape measurements, which is rarer than it should be. We map 59 trees in 5 cities here. The oldest of them is Kongeegen (the King Oak) in Jægerspris Nordskov, at estimated 1,500 to 2,000 years old, based on a 1965 tree-ring investigation.
The Danish dendrological society has surveyed them one by one and filed them under working names: a beech in Frederiksberg Have is registered as Bøgen ved Bådfarten, the beech by the boat trip, which makes it the easiest tree in the city to find. A honey locust has been on record since a gardening magazine featured it in 1941. Assistens cemetery holds five of the sixteen mapped here, and the thickest tree inside its walls is a sycamore, the least exotic species in it. The oldest is Skovfogedegen, a hollow oak 11 km north of the city at the edge of the royal deer park, which three Danish sources date to around the year 1200. The country's most famous oak is not in either city: Kongeegen stands propped and hollow in Jaegerspris Nordskov, the last of three named oaks in that wood, with Storkeegen dead in 1980 and Snoegen in 1991. Two single trees have their own places too: Ambrosius-egen on Tåsinge, redated from 700 to roughly 400 years by a 1997 core sample, and Svalebøgen in Gjerrild, a fused beech failing since a trunk came down in 2022. Twenty-six trees mapped so far, across five places.
