Brussels, 1905: the last stone of the respectable Saint-Michel High School is laid. In one of the building's deserted wings, behind a secret door, a handful of Jesuits secretly set up a tiny cabaret, hidden place of entertainment and, who knows, perhaps even debauchery ? Fascinated by the occult arts and sciences of the strange, they invite magicians, mentalists and other artists of the bizarre from all over the world to perform on stage. The (Trappist) beer flowed freely : « The Mystery Cabaret » was born ! 

The venue is not listed on any map, but has survived two wars and the ravages of time. Exceptionally, it opens its doors to the uninitiated, on invitation only : do not miss this opportunity to discover it, at last !
