It is located in the interior of the northwest side of the fortifications, named after the San Salvatore monastery.
The entrance is from the street "Theotokopoulou" and it is connected to the habitations of the monks by an arcade on the south side. Three construction phases are recognized: initially, there was a small vaulted 15^th century chapel. During the 16^th century, the chapel was extended to the west, and at the end of the Venetian period it took its present form. 
During the Turkish period, it was converted to the mosque of Aga Tzamisi.
The accumulation of valuable archeological findings, collected from excavations but also from donations, created a rich collection that marks the historical route of the Chania Prefecture from the Paleo-Christian period to the Turkish period. Representative samples of this collection are exhibited in the temple of San Salvatore.
The exhibit focuses on the historical and artistic identity of the Prefecture of Chania during the Byzantine and Post-Byzantine periods.
The exhibits were divided in units according to category (mosaics, inscriptions, wall paintings, ceramics, sculptures, coins, ect) and are presented in chronological order, along with information tables and maps.
