bones

Many tourists who fill the bustling streets of Paris do not realize that there is a twisting network of tunnels and caverns deep beneath their feet—and that it is lined with the bones of the dead. These tunnels and caverns are part of the eerie underground world of Paris’s catacombs, which continue for miles on end. More than six million Parisians—nearly three times the population living in the city above—have found their final resting place here. Although Paris’s catacombs often go unseen by the typical tourist, they are a must-see for adventure-seekers and history buffs.
