It's crime time in Paris museums... During the All Saints' Day vacation, on Thursday October 23, 2025, the Cité de l'Architecture is counting on you to solve an investigation and find the murderer hiding there... Are you up to the challenge?

The All Saints' vacation, just before the Cité de l'Architecture et du Patrimoine 'sHalloween party, was supposed to be peaceful... Unfortunately, a heinous crime has been committed under the Gros-Horloge. So you're forced to go to the heart of the museum, in the middle of the evening, to solve the case and catch the murderer.

To celebrateHalloween, the Cité de l'Architecture is inviting us to take part in a life-size game: a thrilling and breathtaking murder party, to be experienced this Thursday, October 23, 2025. Please note that the game is not suitable for children.

The synopsis of the murder party at the Cité de l'Architecture :

" The body of M. Manchette, an international specialist in Viollet-le-Duc, is found lifeless in the museum. Who could have a grudge against this widely recognized scholar? Does his death have anything to do with his work as an architect, teacher and author... or is it his private life that is catching up with him? "

For this perilous investigation, you'll be divided into teams of 6 detectives: groups will be formed on site if there aren't already six participants.

Faced with such a crime, you won't have too many six heads to collect the clues, solve the riddles and discover the culprit. Take a close look at all the suspects, talk to the superintendent, the witness and the suspects to unravel the truth and catch the culprit. A task easier said than done, we agree.
