Wookey Hole

Wookey Hole is a tourist cave in England, on the southern edge of the limestone Mendip hills[?], 3 km from Wells, formed by the action of the River Axe. Especially famous is the Witch of Wookey Hole - a roughly human shaped rock outcrop, reputedly turned to stone by a monk from Glastonbury.

The caves, at a constant 11 deg. C., have been used by humans for around 50,000 years.
