San Pietro, Baroque oratory in Porto Maurizio, Italy.

San Pietro is a baroque oratory in the Porto Maurizio district of Imperia, set in the medieval quarter called Parasio. Its single rectangular hall is covered by a barrel vault, and the walls carry frescoes of the Acts of the Apostles and the Gospels alternating with black-and-white figures of ten apostles. The facade by Giovanni Bossetti has a three-arch loggia on paired columns and a terracotta relief of the papal tiara and keys of Saint Peter.

The first construction is estimated to the 12th or 13th century, though no document fixes the date. In 1599 the building passed to the Compagnia dei Disciplinanti, and its present baroque form dates to the late 18th century, with a facade by Giovanni Bossetti (1789). Between 1790 and 1791 the main door, bell tower, facade, loggia and western stairway were completed.

Since 11 September 1599 the oratory has belonged to the Confraternita di San Pietro Apostolo, which still gathers here. The dark wooden benches installed in 1788-89 run along the whole perimeter so the brothers could sing the Office in alternating choirs. The name comes from the apostle Peter, whose tiara and keys appear in terracotta on the facade.

The oratory is located in the center of Porto Maurizio and easily accessible on foot from the town center. Its position within the municipality of Imperia makes it straightforward for visitors to reach.

The small bell tower stands on an old round watchtower that relayed signals from the Prarola tower and passed them on to other posts inland. The plaque above the side door recalls episodes of the oratory's history that lack contemporary paper documents.
