Probably the most interesting attraction in Paris for thrill seekers is the Catacombs. Each year over 50,000 travelers visit these long narrow tunnels lit only by a string of overhanging bulbs. This gives an eerie light to the thousands of skulls and bones which line the walls and are laid out in ghoulish arraignments.

The empire of the dead was first opened to the public in 1810. Used in the middle ages as quarries, eventually the graveyards and cemeteries of Paris became so overflowing that the bodies had to be moved somewhere. The public health was at stake, and so several million bones were transferred to the catacombs in the biggest remains transfer in history. They were out of the public eye for years, having been deemed indecent and closed in 1830 and late used as the headquarters of the French resistance during the Second World War.

Today you can see the bones arraigned in various stacks of weird artwork, including the chandelier made entirely out of bones and skulls. The Catacombs have been featured on Weird Travels and most Haunted, as their have always been stories relating to the millions of people who wander the passageways as distressed spirits after having been dislocated from their original resting places.
