The Franciscan monastery of San Salvatore, that houses the Byzantine and Post-Byzantine Collection of Chania, was built on the west side of the fortress of Chania, in three phases from the 15th century until the late Venetian period (middle of 17th century). The extensive restoration of the church made it possible to identify more clearly the various building phases of the monument, unify the space, and display its austere, uncluttered architectural features to good effect. The original church, which probably dates from the 15th century, was the small domed section on the east side.
