Scratch beneath Paris's romantic surface and you might just find yourself face-to-face with something a little creepy. Actually, make that creepy times a million. We're referring to the six million skulls held in The Catacombs of Paris, an underground ossuary that has piqued the public's curiosity since as early as the 19th century.
The remains that line the walls are originally from the Holy Innocents' Cemetery, which had been used to bury the dead for ten centuries. In the 18th century, however, locals started getting sick from the cemetery's overuse and the incomplete decomposition of bodies (gross!). This led to the bodies being exhumed and transported to what are now The Catacombs of Paris.
Trabblrs can tour this old 2km underground stone mine in 45 minutes to learn more about Paris's darker past. Don't worry, The Catacombs aren't an invitation to get sick - the skulls and bones have been properly treated. A bout of claustrophobia is more likely.
Meeting point: At the entrance to The Catacombs. A few Metro stops are close by: Raspail on the M4 or M6, Saint-Jacques on the M6, and Mouton-Duvernet on the M4.
Leaders, visitors are limited to 200 at any time. Therefore, you may have to wait. The Catacombs are open every day from 10am to 5pm. It's closed on Mondays and the last admission is at 4pm.
