It's back for its 22nd edition in Paris and Île-de-France: the Nuit des Musées, the big cultural event you can't miss. One night a year, museums, monuments and art spaces across France open their doors for a special evening, and often free!
Hundreds of venues are taking part in this celebration of art: the perfect chance to step off the beaten track and discover the artistic heritage tucked away right in our neighborhoods. In the Val d'Oise, there are indeed many fascinating sites, sometimes little known, waiting for you this Saturday, May 23, 2026!
During this Night of Museums, we’re meeting at Musée Municipal Michel Bourlet, situated in the town of Deuil - La Barre. Opened in 1984 by a local historian, the Michel Bourlet Museum is devoted to the local history of the region, with a permanent route anchored around three main themes: religious life, the illustrious owners and hosts of the great estates, and the economic and sociological evolution.
