The Hôtel Gaillard is a private mansion house in Paris built between 1878 and 1882 by the banker Émile Gaillard to house his collection of medieval and Renaissance artworks. The building is an exceptional example of neo-Renaissance architecture, inspired by the Loire Châteaux of Gien and Blois. The interior decor – the wood carvings and sculptures – are of the finest quality. One superb feature of this building is a safe room – of Art Deco inspiration – surrounded by a moat and accessible via a removable floor. The building is listed as a Historic Monument and the Banque de France will be opening it to the public for the first time in its history.
