The collections of the City Museum are composed of archaeological finds, documents, artefacts and works of art. These different items, which have been added in different moments, narrate the history of the town. In Palazzo di Città the collection describes the historical context of the town and offers visitors a view of some works of art that are of great historical and artistic value, such as: the Bathing Venus, a sculpture in marble dating to 1604, the sole remaining statue of the four that originally adorned the corners of the Rosello Fountain; the groups of wooden figures Fancy Dress in Sassari (1937) and the Procession of the Mysteries (1928), by the sculptor Eugenio Tavolara; and the splendid clock from 1867, which can still be admired. In the Duke's Rooms and Cellars one may see finds which allow us to reconstruct part of the post-medieval urban layout in the area between Palazzo Ducale and Santa Caterina. The archaeological finds come mainly from wells and cisterns; these consist mainly of pottery and objects for everyday use, which were produced locally or imported. These help to tell the story of the life of the citizens between the 15th and 16th and the 18th and 19th centuries. Some narrate the habits and customs of the old owners of the Palazzo.
