Rumskulla oak

The tree is more than 1,000 years old[3] and was first described by Magnus Gabriel Craelius in 1772 in Försök till ett landskaps beskrivning ("Essay in the description of a landscape").

[8] A chain a little higher up prevents the trunk from splitting; the tree is now completely hollow.

Climbing has been forbidden since 1998 and there is a fence around the tree; going closer than 5 metres (16 ft) is not permitted.

[9] The hollow trunk of the tree was the location for sex scenes in I Am Curious (Yellow), a 1967 film by Vilgot Sjöman.

[5][10][11] The film was controversial when first released, including being banned in Massachusetts; in a case that went all the way to the Supreme Court of the United States, it was ultimately determined not to be obscene.
