The Parish Church of St. Peter the Apostle is located in the center of the village, in a high position overlooking the surrounding area. Its existence is attested as early as the 12th century, but the present building was built from the 16th century following the re-foundation of Nuraminis (1539), with various phases of expansion and restoration. The facade, in Sardinian Gothic style, is characterized by the flat crenellated finial with the stone cross. In the center of the facade is the large rose window that consists of a large painted stained glass window depicting a scene from the Gospel of John. The wooden door is hinged on two smooth jambs, culminated by the decorated capitals supporting the lintel. Above towers the niche with the statue of the patron saint placed in 1952 to replace the previous one, which was destroyed by a fall. On the left stands the square-bore bell tower built in the 17th century, the top of which is adorned with a pierced cornice. It has a Latin cross plan, with a single barrel-vaulted nave, from which four chapels open on each side and a deep chancel. On the left, on the third arch, a marble pulpit from 1848 stands out. On the back wall, an acute archway introduces the raised, star-vaulted chancel. In it stands the high altar, centrally surmounted by the oval painting depicting the patron saint Peter the Apostle: composed of polychrome marble and dating from 1848, it conceals from view a small room behind, which now houses a valuable and rare pipe organ from 1772. The first chapel on the right is that of the baptismal font and houses a marble baptistery from 1830. Finally, of interest is the chapel of Our Lady of the Rosary, whose 19th-century marble altar is surmounted by a 17th-century wooden altarpiece, on the left of which are four figured marble fragments inscribed in Greek, part of a 10th-century AD ciborium that probably belonged to the vanished Byzantine church of St. Constantine.
