The church of San Pietro, built outside the city walls, is currently located in the center of the village and is a typical example of the mixture of styles and collaboration of intent that characterized religious architecture in medieval Sardinia. The building, built in Romanesque times, was consecrated in 1377, as shown by the epigraph in the Sardinian language kept inside it and once placed above the right portal at the entrance. MCCCLXXVII CUNSACRATA ECCLESIA DE SANCTO PEDRU MARTIRI APOSTOLU PRESENTE GIREMEO DE SERRA PODESTADI DE SELORI CONVITADU DE SU POPULU A BOLONTADI COMUNU. The iconographic layout presents a basilical body lacking a nave, presumably due to the fact that the church was initially conceived with a single nave and only later enriched with the right aisle (as evidenced by some studies by R. Salinas). The church, recently restored and reopened for worship, has a surface area of 180 sq. m. The very simple facade is surmounted by a bell gable whose bell is dated 1577. The interior has two naves with trussed roofs ending in cross-vaulted chapels. The major chapel is dedicated to St. Peter, the minor chapel, on the right, to the Virgin of Pity. Of the original furnishings, there is still a gilded wooden altar from the early 1700s, some 18th-century canvases that were part of a polyptych that was destroyed in the 1960s, and a wooden simulacrum of St. Peter, which some date to the sec. XIV. From this church comes the large altarpiece of St. Eligius, the work of an unknown author conventionally known as the “Master of Sanluri” and dating from the early 1500s, currently housed in the National Picture Gallery in Cagliari.
