Grand Siècle museum — Saint-Cloud

The Hauts-de-Seine department has entrusted the rehabilitation and restructuring of the Caserne Sully to the consortium led by Fayat Bâtiment with Rudy Ricciotti Architecte, under a public design-build-performance contract, to create the Musée du Grand Siècle. Set in the lower part of the Domaine national de Saint-Cloud, the former barracks comprises a large 6,300 m² building from the reign of Charles X (1825–1827) and the 1,100 m² Officers' Pavilion.

The museum will present works and objets d'art from the major collection assembled by Pierre Rosenberg, former director of the Louvre; multimedia will provide digital interpretation for every audience. The architectural approach calls for preserving the authentic character of the place and a rigorous restoration.

The Charles X building, on three levels, houses the heart of the museum route and the permanent displays; a newly created basement level will hold 50 parking spaces, plant rooms, the 120-seat auditorium and the immersive rooms. The Officers' Pavilion, given over to the research centre, retains its façades, roofs and floors; the new 1,300 m² building, the Belvédère, will house temporary exhibitions and catering areas.
