The Church of San Pietro di Ponte is located within the municipal cemetery of Quartu Sant'Elena. This ancient church was originally built in the 12th century and then rebuilt in the late 13th century by skilled late-Romanesque craftsmen of the Giudicato of Cagliari.
The site corresponds to the ancient Quarto Suso, a short distance from a Roman bridge along the road from Carales to Ferraria.
The building, characterised by a single nave with a southeast-facing apse, has a façade adorned with limestone and sandstone ashlars. The ribbed bell tower, with elegant small arches and ogival light, rises majestically above the façade, while the central portal, now curved, was originally intended to be architraved and fitted with an overhead arch.
On the outside of the church, along the façade and sides, there are pilasters, pilasters and hanging arches finely decorated with geometric motifs and zoo-anthropomorphic symbols. In particular, on the façade divided into three sections, one can see rows of ashlars with numerous accommodations for ceramic basins, although most of them have been lost over time.
