Into the deep of Paris

The center of Paris hides a lot of secrets under its ground. Beneath telecom tunnels, sewers and metro there is a 300-km long chain of catacombs. It is illegal and dangerous to wander around a stone labyrinth full of human bones that were exhumed since the XVIII century from overflown cemeteries. In this unfriendly environment, Parisians have parties, make art and find real freedom.
