If there’s a chance to see really famous ghosts, would you take it? At the Père Lachaise Cemetery, you just might. Said to be among the most haunted cemeteries not only in Europe, but in the entire world, it is the burial ground of several well-known names like Edith Piaf, Oscar Wilde, Jim Morrison, Molière, Marcel Proust, Balzac, Camille Pissaro, and several others.

Why it’s so scary:

Visitors and tourists have reported overwhelming eerie feelings, shivers running up and down their spine, and various ghastly sightings. Some, however, say that the cemetery leaves them filled with a deep sense of unnatural calm—not the zen-type though, but more the supernatural kind.

What to look out for:

Watch out for ghostly apparitions and strange orbs which could sometimes appear in photos taken around the cemetery. If you’re lucky, Chopin might even pop in for a visit. He’s the most widely seen famous ghost in Père Lachaise, as well as Jim Morrison who is also said to appear in photographs near his grave. Maybe you can coax them for autographs?
