For the Journées du patrimoine 2024, discover the Hôtel de Beauvais, home to the Paris Administrative Court of Appeal since 2003. Built in 1654 for Catherine de Beauvais, this listed monument is brimming with trompe-l'œil and false symmetry. Join us on the weekend of September 21 and 22, 2024, for this exceptional, not-to-be-missed opening.
