This year's Journées du Patrimoine (Heritage Days) are not to be missed in Paris and the Île-de-France region on Saturday September 20 and Sunday September 21, 2025, and promise to give you two exciting days with a rich and exclusive program.

For those with a passion for politics, theNational Assembly is the place to be. As part of the Journées du Patrimoine, the institution is once again opening its doors to reveal what goes on behind the scenes of power, and the national heritage preserved in this mecca of French politics.

Built in 1728 by the Duchesse de Bourbon, the two buildings of theAssemblée Nationale were soon considered"the city's greatest ornament after the royal houses". Today, the two buildings house the Chamber of Deputies and the residence of the President of the Assembly. While the Palais underwent major transformations in the 19th century, such as the creation ofa "sugar loaf" roof and a peristyle of twelve columns, which totally altered its architecture, drawings and models preserved in the library allow us to better appreciate the building's primary style, similar to the Grand Trianon. Please note, however, that admission is by registration only. So don't forget to register in advance on the Assemblée Nationale website.
