Church Santi Gervasio e Protasio, Classical church in Pavia, Italy.

Church Santi Gervasio e Protasio is a church building in Pavia with classical architectural features, including a prominent semi-circular window and curved volute elements on the facade. The interior contains a valuable organ and holds various artistic works.

The church is traditionally held to be the oldest in Pavia, built in early Christian times on a Roman suburban necropolis. Excavations in 1949 in the square in front uncovered parts of the apse of a basilica from the decades around 500. The first bishops of Pavia, Syrus and Pompeus, were buried here, as were the Lombard kings Cleph and Authari. Cluniac Benedictines rebuilt it entirely in the 12th century; Franciscans gave it its present form between 1712 and 1718, reversing the entrance and replacing the Romanesque facade with a new apse.

The name comes from the Milanese martyrs Gervasius and Protasius, whose relics were found in 386 and partly brought to Pavia by Bishop Invenzio. In the chapel of San Siro, a late-16th-century fresco cycle covering the walls was rediscovered and restored only in 2004, considered the most important artistic find in Pavia of that century.

The unfinished 18th-century facade faces the small square, with a three-light portico and a tympanum left without plaster; the organ sits above the atrium, behind three windows of the counter-facade. The single barrel-vaulted hall has six side chapels, three per side, so the San Siro chapel with the baptistery is the second on the left. The Romanesque bell tower, divided into five orders with a bifora bell cell, is best seen from the sides of the building.

The organ above the entrance atrium is not the only musical trace: the third chapel on the left belonged to the noble Botta Adorno family and holds the tomb of Antoniotto Botta Adorno, a senior Habsburg official. The chapel was dedicated to Saint Anthony of Padua, a dedication typical of a Franciscan building.
