This tree is called "Kvilleken". The Kvilleken (Kvill's Oak), named after the closeby hamlet of Norra Kvill, is Europe's thickest oak. Like all old oak trees, the tree has a hollow trunk, so it is impossible to determine its age by simply counting tree rings.
A part of the trunk must have died off a long time ago and is currently attached to the rest of the trunk using cables, so the tree cannot collapse further. Although many trees claim to be over a thousand years old, a magical age like this is not so unlikely for this particular tree.
The girth of the tree is 14.75 m measured at a height of 1.30 m (Apr 9, 2006, Jeroen Pater). Its height is around 16.00 m (Jul 25, 2000, measurement method unknown, Jeroen Philippona). This tree was planted in 1500, which makes it exactly 513 years old (Tim B, Oct 1, 2011).
