Ceci n'est pas un musée  is a miniature cultural institution in Montreal Quebec, Canada, co-founded with Natalija Subotincic. The dioramas shown here were started during the first COVID-19 lock-down (March 2020), and displayed in three windows facing rue de Bullion, as a gift to the street and our neighbourhood.  New dioramas replace older ones in these windows, while the older ones are moved indoors to live in the Museum's (not a museum's) Diorama Room.
