The Great Treasury (318 sq. m. of floor space) is a spacious and at the same time elegant hall, the vault of which is supported by four huge pillars. Its shape is similar to that of the Great Assembly Hall, which is located directly above it. The Treasury is situated on the ground floor of the castle, conveniently close to the restaurant Café Zamek. Its windows look out over the central axis of the restored Royal Gardens. The French windows lead out onto the garden terrace, which is used in summer.
