This is one of the oldest parish churches in Cagliari and documents date it back as early as the 14th century. It was built in the typical Catalan-Gothic style of the time. It underwent restoration works in the 18th and then the 19th century, which added the Neo-Classical façade, based on a project by architect Gaetano Cima. The main structure has preserved many Gothic elements, e.g. the steeple, the apse behind the main altar and four side chapels. It's worth to walk in to have a look, while walking around the busy shopping streets of Villanova.
