The Hypogeum in Ħal-Saflieni, Paola, Malta, is a subterranean structure excavated c. 2500 B.C. Thought to be originally a sanctuary, it became a necropolis in prehistoric times. It is the only prehistoric underground temple in the world. The Hypogeum was depicted on a 2 cents 5 mils stamp issued in the Maltese Islands in 1980 to commemorate the acceptance by UNESCO of this unique structure in the World Heritage Site list. It was closed to visitors between 1992 and 1996 for restoration works.
