The Winner of This Competition Will Spend Halloween in What Is Basically the World’s Biggest Grave

Airbnb is offering up its most ghoulish accommodation yet — the underground catacombs of Paris, where the skulls and skeletons of over 6 million dead are entombed. And you can now vie for the chance to sleep spend Halloween night there.

All you need to do is explain, before Oct. 20, why you would be courageous enough to complete the overnight stay.

“Before bedtime, a storyteller will have you spellbound with fascinating tales from the catacombs, guaranteed to produce nightmares. Finally, enjoy dawn with the dead, as you become the only living person ever to wake up in the Paris catacombs,” Airbnb says. Guests will also get a private concert and a “a dazzling culinary experience” in the mass tomb.

The underground tunnels were first built in the 1780s after more conventional cemeteries, filled to overflowing, became a public health hazard. Over time, they became a curiosity and today are visited by hundreds of thousands of tourists annually.
