The European Heritage Days, created in 1984 by the French Ministry of Culture, are a not-to-be-missed annual event for history and culture lovers. Every third weekend in September, monuments, museums, parks and other heritage sites open their doors to the public, often free of charge, to offer a glimpse into the history of France.
In Paris and the Île-de-France region, the Journées du Patrimoine 2026 promise once again a rich and varied lineup. The iconic places not to miss include, of course, the Palais de l'Élysée, the behind-the-scenes access to the Opéra Garnier, and the many guided tours in the national museums.
The Maison Jean Monnet in Bazoches-sur-Guyonne is one of the Yvelines department's most important historical sites. The former residence of the father of Europe, Jean Monnet, this house, now a museum, is a place of remembrance dedicated to one of the European Union's leading architects.
