The Temples of Humankind are a collection of subterranean temples buried 30 metres (100 ft) underground built by the Federation of Damanhur. They are decorated in several motifs stressing peaceful human collaboration. The Temples are located in the foothills of the Alps in northern Italy, 50 kilometres (30 mi) from Turin, in the valley of Valchiusella.
The temples were created under the direction of Oberto Airaudi who, having claimed visions of ancient temples at age 10 from a previous life, began excavation and building in August 1978. By 1991 most of the chambers were reportedly complete when Italian police, acting on a tip from villagers, conducted a raid on the Temples. However, since the temples were so well hidden, police were unable to locate them until state prosecutor Bruno Tinti threatened "show us these temples or we will dynamite the entire hillside."[1] Eventually the Italian government reportedly gave them retroactive excavation and erection privileges and the Temples are now open to visitors.
