The small chapel was obtained from a palace room in 1913.
The altar, of the late XVIIIc., was adapted to the room. The small altar-piece by Agostino Ugolini (1756-1824), signed and dated 1795, is dedicated to the Immaculate Virgin, who, in glory with the Infant Jesus, treads on the dragon; below, in prayer, there are the Saints Louis Gonzaga and Francis of Sales.

The altar.

The furniture is completed by a beautiful sacristy wash-basin (Venetia, half of the XVIIIc.) and by a precious home little altar, made up of a crucifix and of two amber candlesticks with ivory inlays of the Baltic area (Danzig and Koenigsberg), to be dated in the second half of the XVIIc., dedicated to the sacred Heart of Jesus.
