The Vela Spila cave (Croatian: Vela Spila, "Big Cave") is situated above the town of Vela Luka on the island of Korčula, in Croatia on Pinski Rat hill at an elevation of approximately 130 m (430 ft). The cave consists of an elliptically shaped cavern that measures 40 m (130 ft) in length, 17 m (56 ft) in height, and is approximately 40 m (130 ft) wide. There are, similar to the Brillenhöhle in Germany, two openings in the roof of the cave which were caused by collapse at an as yet undetermined time.
