Secret societies have always been part of conspiracy theories and widely recognized as myths. In fact, few of these really exist for lack of any reasonable evidence. But it was only recently that evidence hinting to a supposedly still functioning underground society was said to have been discovered in the Parisian catacombs. Here's what Paris's police found during a visit to the catacombs... Paris's catacombs are a large trail network of former mining tunnels. What are now the catacombs of Paris used to be a long network of mines for limestone quarries from as far back as the 13th century. Toward the 17th century, Paris began facing a huge problem with its burial system to the point where the city was overflowing with bodies. At which point, it was considered best to relocate the remains of about 6 million people to the underground tunnel system, which now serve as the catacombs.

Only about a mile of the supposed 200 mile long network of the ossuary is open for public visitation.

Sometime between 1814 and 1815, the catacombs were opened up for public visitation, although a majority of the network is restricted to the public till date. These quarantined pockets are regularly patrolled by the police and trespassers are fined with about ₹5000, if found breaching.

But that still doesn't stop enthusiastic city explorers from heading to restricted pockets.

In fact, one of the more cumbersome problems that the city has is with mischievous citizens constantly breaking into the quarantined areas for everything from parties to just usual exploration runs. The colloquial term for these guys is 'cataphile', and there is a huge community of them.
