Can you imagine the Mona Lisa stepping out of her frame to haunt the halls of the Louvre, or the statues at the Grévin Museum coming to life for a single Halloween night? In Paris and the Île-de-France, museums and castles transform for the occasion into places thick with mystery, where art meets the uncanny. Between unconventional tours, thrillingly eerie experiences and playful activities, visitors encounter unexpected creatures and stories that are as funny as they are unsettling.
Once again this year, Halloween is coming to cultural venues! Young and old alike are invited to enjoy themed workshops, animated tours, and costume games in a festive and slightly spine-tingling atmosphere. Museums and castles in the Paris region are pulling out all the stops to offer families original outings that combine discovering heritage with the pleasure of a gentle scare.
Zombies, vampires, fairies, goblins, witches, knights, ghosts and monsters of all kinds invade museums and castles. But these creatures aren't always so scary: they often even make us laugh! Through special activities, games, exhibitions, tastings, guided tours and walks, these little monsters gradually reveal themselves, and make our experience a whole lot more fun.
