Palais des congrès de Royan, Convention center in Royan, France

The Palais des congrès de Royan is a convention center with a cubic reinforced concrete structure and external diagonal staircases. The building contains an adjustable performance hall, ten meeting rooms, a reception space, and dining facilities for various events.

The building was constructed between 1954 and 1957 by architect Claude Ferret. It stands as a key example of post-war modern architecture and shaped the city's reconstruction after the Second World War.

The building's name refers to its original function as a congress centre, with a modular performance hall, ten commission rooms, a reception hall and a restaurant. A mural for the new stairwell was commissioned from the artist Nadu Marsaudon in 1977. Since 2023 the ground floor has housed the municipal centre for the interpretation of architecture and heritage.

The center sits directly on the coast overlooking the Gironde estuary and is easily accessible on foot. Visitors should know that its waterfront location means access can vary depending on the season and weather conditions.

The 1972-1975 conversion by Marc Quentin and Michel Legrand added a transparent glass cube over the gardens and closed the building off from the Gironde estuary with a glass wall. A 1977 mural for the new stairwell was commissioned from the artist Nadu Marsaudon. The glass cube was later slated for demolition, and the renovated building was inaugurated on 26 June 2023.
