Skovfogedegen is an old hollow oak tree in Klampenborg north of Copenhagen. The tree has existed since about 1200. Even though the wood in the middle of the tree’s stem has been ripped away, the tree continues as the transport of water and nutrition takes place in the growth layer just below the bark. The oak was named ‘Skovfogedegen’ because it stands at the forester’s house: Klampehus. Skovfoged means forester in Danish. In the past, foresters were entitled to sell schnapps, and one of the foresters used the hollow tree as a public house.
