For a year from September 2005, under the nose of the Panthéon's unsuspecting security officials, a group of intrepid "illegal restorers" set up a secret workshop and lounge in a cavity under the building's famous dome. Under the supervision of group member Jean-Baptiste Viot, a professional clockmaker, they pieced apart and repaired the antique clock that had been left to rust in the building since the 1960s. Only when their clandestine revamp of the elaborate timepiece had been completed did they reveal themselves.That is awesome - not only did they sneak into the building under the noses of the curators, but they restored the clock and built themselves a small living room, which is rather chic. They were recently cleared by the Paris Court of Justice of breaking any laws.
