This huge cave consists of three chambers reached via 90 steps. Inside, ceilings soar up to 25m high while some rather disco-festive lighting illuminates a wacky array of stalactites. Among the stalactites of the first hall, scores of gnomes appear to be holding a meeting. The cave derives its name from the role it played during the 13th-century battles with the Mongolians when locals stored wooden stakes, used to destroy invading ships, in the third chamber here.
