Consecrated in 1377, the church of St. Peter the Apostle was for a time the “parish church” of Sanluri. Located in the town’s central square, it is a typical example of the mixture of styles and cooperation of purpose that characterized religious architecture in medieval Sardinia.
In the simple facade, topped by a small ribbed bell tower whose bell is dated 1577, are the two entrance portals.
The interior is divided into two naves with wooden roofing, divided by two wide arches.
Above the right portal was an inscription stating that the church was consecrated in 1377. The inscription in the Sardinian language, currently kept inside the building, bears the name of the Podesta of the time (Giremeo de Serra) and testifies to the existence of Sanluri as an autonomous rural commune, as the church was built by the will of the people gathered in assembly.
