Traces of the original Romanesque layout, attributable to the 13th century, can still be read very clearly in the building’s facade. Between the late 1400s and the early 1500s the church was entirely rebuilt according to the typical features of the late Gothic style: a nave covered with wooden trusses, divided by round-arched diaphragm arches and the presbytery (capilla mayor) narrower and lower with a star vault and hanging gem. Inside is a wooden compass with chancel above, the work of Sardinian craftsmen active in the 18th century. Numerous works of art are preserved, such as the retable placed on the high altar, made in 1518 by the painter Pietro Cavaro, the greatest exponent of the family of painters known as the “Stampace School,” named after the Cagliari district in which the workshop was based. Commissioned by the Lords of Mara Arbarei, the ancient Villamar, the Aymerichs.
