Built in the 13th century in late Romanesque style, it represents a significant example of Sardinian religious architecture. Originally built with a single nave, it was enlarged in 1303 with the addition of two side aisles, substantially modifying its original structure. The façade of the building features architectural elements of particular interest: a wooden doorway of Gothic-Aragonese workmanship, testifying to the cultural influence of the period, and a circular rose window with stained glass, a typical element of Romanesque architecture. The rear is characterised by the presence of a massive bell tower, which accentuates its verticality and visibility in the urban context. Despite the structural changes it has undergone over the centuries, it still retains the original apse and portal, valuable elements for understanding the original architectural layout. Inside, behind the altar, there are painted panels of considerable artistic value, which enrich the building's cultural heritage. Not only is it an important place of worship, but it also constitutes tangible evidence of the architectural and artistic evolution of medieval Sardinia.
