For All Saints' Day 2026, Paradox Museum Paris shifts into Halloween mode with a transformation inspired by the dark, mysterious universe of Edgar Allan Poe. From the set design to the scavenger hunt, including the illusions, the raven-themed atmosphere, and a room dedicated to the author, the entire museum invites visitors to follow the thread of the mystery. From October 24 to 31, this mood stays open until midnight with eight special late-night sessions, powered by magic from the magician Donovan, hypnosis, and mind-bending experiences that blur the lines of reality.
