San Pietro in Banchi, Genoa, Catholic church in central Genoa, Italy.

San Pietro in Banchi is a central-plan church raised on a base that houses shops and storerooms, set above the level of Piazza Banchi and reached by a broad staircase. Its facade has a three-arch portico with frescoed cross vaults and two small bell towers at the sides; the planned decoration was replaced by painted architectural motifs, and the other walls keep rough neutral-toned plaster.

A church existed here by 862, founded by a cleric named Agostino as a monastic cell of Bobbio abbey; it passed to Santo Stefano and in 1125 to the cathedral of San Lorenzo for 50 lire. Guelph-Ghibelline fighting burned it in 1398, and the Lomellini built a palace on the site. The present church was designed from 1572, financed by renting and selling the shops and warehouses beneath it, and completed by 1585 by Andrea Ceresola and Giovanni Ponzello.

The church is also known as San Pietro della Porta, after a gate in the Carolingian walls built in 804 at the mouth of the Soziglia stream. Since 1984 the adjoining rooms have housed the Centro Banchi, founded by don Marco Granara and lay volunteers, which keeps the church open for visitors and runs cultural and interreligious activities.

The church stands on Piazza Banchi in the Molo quarter, raised on a base of shops and warehouses and reached from the square by a broad scenic staircase. The facade portico has three arches with cross vaults, and the interior is a central plan under a dome. Volunteers of the Centro Banchi, active in the adjoining rooms since 1984, keep the church open for visitors.

The facade's decoration was never finished; around the mid-17th century Giovanni Battista Baiardo replaced it with painted architectural motifs, still visible above the three-arched portico. The other sides keep rough plaster in neutral tones. The church rests on a base of shops and warehouses whose rent and sale paid for its construction.
