San Gavino is characterized by a structure typical of agricultural centers, made up of large houses with wide arched entrances and spacious courtyards.The buildings in the historic center are mainly typical Campidanese architecture made of unbaked earth, nowadays the subject of recovery and enhancement also for tourism purposes. For further knowledge, in the historic center, here is the sa Moba sarda museum, which tells with pictures and tools the agricultural culture characteristic of the center until the 1920s, when industrialization began. The San Gavino foundry was its emblem and important economic reality. Now disused, it is a destination for industrial archaeology enthusiasts. Since the 15th century, the center has stood out for saffron cultivation. Production of ‘red gold’ now covers much of the national production and is exported across borders. Processing has been handed down over the centuries through generations and is echoed every year for ten days in November with the International Saffron Fair. In addition to saffron, traditional flavors (soups, meats, semolina bread, and delicious desserts) can be enjoyed, and San Gavino is also an important center for rice cultivation. The church of St. Gavino Martyr, once a parish church, was built in 1347 at the behest of Mariano IV of Arborea. In addition to the remains of the original Gothic structure, of great interest are the four corbels of the apse, where historian Casula discovered coeval portraits of Mariano himself, his son (and heir) Ugone III, his daughter Eleonora, and her husband Brancaleone Doria. The exterior structure is sober; the interior has a single nave. In the mid-20th century, the floor was renovated, which, according to legend, hides the tombs of the last Arborensian rulers. The sangavinese territory frequented since prehistoric times, has returned various Roman remains, including a necropolis and the peristyle of a villa.
