The Internet has ruined the Parisian catacomb subculture. Deeper down, it was mostly oddballs and the eccentric tourist, street punks and bored rich partying together between stacked skulls and subterranean graffiti. Now that any teen dork can download a map and wobble on down, just like Paris above, the underground city has become touristy.
Not quite yet though. There are still a few real moles squabbling illegally in 155 miles of the partially flooded tunnels.
See this recent WSJ video to meet them and check out the best of Flickr cataphiles below.
