A secret underground temple, occupying nearly 300,000 cubic feet, has been outed and taken over by Italian police, who were investigating the owner for tax evasion. Built underneath a normal-looking house near Turin, Italy, the underground building is made up of nine ornately decorated temples sprawled over nine levels.

[T]he 'Temples of Damanhur' are not the great legacy of some long-lost civilisation, they are the work of a 57-year-old former insurance broker from northern Italy who, inspired by a childhood vision, began digging into the rock.
