デヒェン洞窟

The Dechen Cave in Iserlohn, Germany, is one of the most visited show caves in Germany. It is located in the northern part of the Sauerland at Iserlohn. 360 metres of the 870-metre long cave have been laid out for visitors, beginning at the spot where, in 1868, the cave was discovered by two railway workers. The workers dropped a hammer into a rock crevice which turned out to be the entrance to a dripstone cave when they were searching for the lost tool.
