The parish church of San Pietro is one of the few churches in the province of Cagliari in which the typical features of the Catalan-Gothic style are represented. An important ancient Greek epigraph in white marble, which was part of a side door step until the middle of the last century, is now kept in St. John’s Church. The inscription was studied and read by Spano, Plaza, Cavedoni, Solmi and transcribed by Taramelli in which the following is stated: “In the name of the father, the son and the holy spirit, I Nispella Diocote have built the temple of the holy bishops and apostles Peter and Paul of John the Baptist and the virgin martyr Barbara, so that with the help of their prayers the Lord God may grant me forgiveness for my sins.” Nispella was the wife of the protospatron Togotorius who lived between the year 1000 and 1050. From these few data, it is possible to date the first planting of the church in the Byzantine era around the year. Over the centuries the original layout underwent multiple transformations, mostly extensions, leading the church to the Gothic-Catalan forms it still retains today.
