St. Peter's Church (Chiesa di San Pietro Somaldi), Lucca

Saint Peter’s Church, or San Pietro Somaldi, is a historic Roman Catholic church located in the square of the same name in central Lucca. With origins tracing back to the Lombard era, the church was founded in 763 by Bishop Sumualdo (also referred to as Summal), from whom it derives its name. At one time, the church was under the possession of the Lombard king Aistulf before being transferred to the painter Auriperto.

The church underwent significant reconstruction beginning in the 12th century, a process that extended into the 14th century. Its current form showcases a mix of Romanesque and Gothic architectural elements, characteristic of Lucca’s ecclesiastical style. The brick apse, dating from the 14th century, contrasts with the sandstone façade, which features sparse white stripes and ends with a blind arcade adorned with swollen and foliated capitals. The façade, completed in the second half of the 13th century, includes a central portal of particular artistic significance: the lintel above the entrance, created by Guido Bigarelli da Como in 1248, depicts The Delivery of the Keys to Peter.

Inside, the church is structured with three naves supported by sturdy pillars. While much of the church’s original furnishings have not survived, the interior houses a selection of 17th-century paintings alongside a few notable 19th-century works. Among its most treasured features is the 17th-century organ crafted by the renowned Luccan organ builder Domenico Cacioli. This organ, once played by Giacomo Puccini before his move to Milan, still bears his signature.

San Pietro Somaldi remains a significant landmark within Lucca, not only for its architectural beauty and historical roots but also for its cultural legacy tied to one of Italy’s greatest composers. Today, the church stands as a reminder of the city’s deep religious and artistic heritage, drawing visitors with its blend of history, art, and music.
