Subterrainean Paris is made up of old quarries, catacombs, a giant sewer network, and Métro tunnels. This is a look into the subterranean world that exists under Europe's most splendid city.
The movie "Urban Speleo" will be shown on April 6th at the Theater Aux Arcades in Maastricht (The Netherlands). Doors will open at 9.00 PM.
