San Pietro, Romanesque parish church in Minturno, Italy

San Pietro is a parish church in Minturno with a west-facing gabled facade preceded by a five-arch portico: four slightly pointed side arches and a smaller round-arched central one. The bell tower rises above the central arch in three tiers, each with a marble-columned double-arched window. Inside, a basilical plan of three naves has eight pointed arches on reused columns, a carved wooden coffered ceiling from 1851, and two Baroque side chapels with stucco and inlaid marble.

Pope Leo III had the church built around the 9th century, enlarging an earlier structure probably of the 4th–5th century. It was rebuilt in the 12th century and reworked in the 16th and 18th centuries, when Baroque decoration was added while the medieval layout was kept. It was the cathedral of the diocese of Minturno, united with Formia in 590 and later with the archdiocese of Gaeta.

The interior displays wooden coffered ceilings and side chapels decorated with marble inlays, including a Last Supper painting by Andrea Sabatini. These artworks shape the appearance and reflect the creative traditions that developed here over time.

The parish is entrusted to the archdiocesan clergy of Gaeta. The church stands in the centre of Minturno, with its west-facing facade and five-arch portico opening onto the street. The 13th-century church of the Congrega del Rosario and its crypt lie behind the rear wall of the choir, reached from inside the building.

The 13th-century Virgo lactans fresco behind the main altar is set into the case of the Consoli organ of 2008, so the painting and the instrument share one structure. The wooden coffered ceiling of the central nave dates from 1851. The church keeps the statue of the Madonna delle Grazie (1825), patron of Minturno since 1850 and crowned in 2008 by Archbishop Fabio Bernardo D'Onorio.
