The Diocesan Museum of Sacred Art is located in the underground spaces of the Cathedral, the crypts of the ancient Romanesque church over which the later church of Sant’Antonio Abate was erected. These spaces were restored to create the rooms of the museum, which conserves a number of the liturgical furnishings of the Cathedral.

This “Treasure of the Cathedral” is an integral part of the history of the Diocese of Ampurias: liturgical objects in silver, Baroque altar crosses, incense burners, reliquaries and ceremonial vestments, mitres and candelabras. Other fine pieces include wooden statues from the Lombard-Emilian school, such as the Madonna of Salasgiu and the statue of the patron saint. 

The museum exhibits the other paintings by the Master of Castelsardo: San Michele, the Four Apostles and the Trinity, which were part of the original retable along with the current altarpiece of the cathedral. These panels are all painted on a gold background, and the unmistakable style of the Master can be seen in the details, such as the contrast between the disposition of masses in the faces of the subjects and the decorative parts in relief.
