Among the late Gothic buildings in southern Sardinia, the parish church of San Giorgio is one of the most interesting: completed in 1567, it has a horizontal terminal facade with battlements. The interior space has a single nave flanked by Gothic-style chapels with pointed vaults. The chancel is lower and narrower than the nave with a square base, whose cross vault has a large hanging gem at the keystone. Notable elements are the relief with St. George on horseback and Christ on the Cross in the central gem of the last chapel on the left, modeled after the Nicodemus Crucifix of Oristano. Preserved at the side entrance is the ancient Roman milestone (Septimius Severus era), the origin of the name of the modern settlement. St. George is the patron saint, whose feast day falls on April 23.
