San Rocco, Baroque church in Turin, Italy.

San Rocco is a baroque church on Via San Francesco d'Assisi in Turin, built on an octagonal plan; its dome and drum were left unfinished. The facade, squeezed between neighbouring houses, was rebuilt in 1890 to a design by engineer Carlo Velasco, with two orders of pilasters and, in niches flanking the entrance, statues of San Rocco and Sant'Espedito added in 1924. Inside, twenty paired columns carry the entablature, drum and lantern, and eight windows open in the frescoed octagonal dome.

Construction began in 1667 under architect Francesco Lanfranchi after the San Rocco confraternity had outgrown their previous home. This new building gave the growing group a dedicated space for their gatherings and religious life.

The confraternity took its name from Saint Roch, invoked against the plague, and from its founding purpose: burying abandoned corpses. In 1620 members travelled to Arles to obtain a relic of the saint, later placed in a crystal urn donated by Maria Cristina of Savoy beneath the altar table. In the underground chapel, inscriptions on the walls recall bourgeois and merchant families once buried there.

The facade is squeezed between neighbouring houses on Via San Francesco d'Assisi, so look for the two niches holding the statues of San Rocco and Sant'Espedito, added in 1924. The octagonal dome and its drum were never completed. The interior is dominated by an octagonal dome with eight windows and twenty paired columns.

The confraternity obtained a relic of Saint Roch from Arles in 1620; it was placed in a crystal urn donated by Madama Reale Maria Cristina beneath the altar table. The brothers also buried abandoned corpses, and in the underground chapel lie a Parisian seamstress who drowned herself in the Po and wealthy local families whose tomb inscriptions remain on the walls.
