Getting out!
The manhole opens on a street sidewalk in the center of Paris. This is one of the secret access shafts to the off-limit underground network.
Catacombs of Paris (off-limit area), about 20 meters (60 feet) underground, under Paris city center.
This is a part of the 200 Km network of ancient tunnels not opened to the public, but regularly visited by trespassing urban cavers called "cataphiles". See more information in the description of the photo album.
