San Pietro, Reggio Emilia, Baroque church building in Reggio Emilia, Italy.

San Pietro is a Baroque church on Via Emilia San Pietro in Reggio Emilia, built from 1586 on a design by Giulio della Torre and completed with its facade in 1782. The interior is a single hall-like nave, the Counter-Reformation aula layout, lit by the large windows of the presbytery and dome. Stucco and gilding fill the interior; beside the presbytery stand two cantorie, one holding Domenico Traeri's organ of 1712, flanked by twisted columns recalling the Confession Altar of St Peter's in Rome.

The church was first documented in 1140 and took its present form beginning in 1586 when architect Giulio della Torre from Bologna oversaw construction. This rebuilding transformed it into the Baroque structure visitors see today.

The church is the seat of the parish of Saints Peter the Apostle and Prosperus Bishop. Its name links it to the medieval church-monastery of Saints Pietro and Prospero attested in 1140. Inside, look for the two cantorie flanking the presbytery, one holding a 1712 organ by Domenico Traeri, framed by twisted columns recalling the Altar of the Confession in St. Peter's in Rome.

The entrance is on Via Emilia San Pietro, while the address Via Campo Samarotto 1 refers to the side facing the cloisters. Inside, the two cantorie flank the presbytery, and the organ by Domenico Traeri of 1712 stands in one of them. The large windows of the presbytery and dome light the hall.

The larger cloister, built about sixty years after the small one under Prospero and Francesco Pacchioni, follows the courtyard of Palazzo Te in Mantua by Giulio Romano. The organ in one of the two cantorie beside the presbytery is the work of Domenico Traeri, dated 1712.
