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 total volume of this tree was calculated to be 60 cubic metres, the third largest volume of all trees (and oaks) of Sweden.
