Palazzo Ducale

The cathedral was built in the 13th century and enlarged in Catalan Gothic style from 1480; there's a monument to the Duca di Moriana inside. The façade, belonging to the Baroque Spanish colonial restorations of 1650–1723, has a rectangular portico surmounted by three niches housing statues of saints. The bell tower is in Romanesque style.

Entering from Corso Vittorio Emanuele II visitors could see the interiors of the Palazzo di Città including the ball room, the historic Civic Theatre. Another entrance is from Via Sebastiano Satta through the tourist information office. This part presents some Sardinian costumes and two works of Eugenio Tavolara depicting the Carnival and the Holy Week in Sassari.

There are still some traces there of its initial Renaissance façade.
