Sant'Agostino, Turin, Medieval Catholic church in Turin, Italy

Sant'Agostino is a Catholic church located in Turin's historic center, featuring a stone facade and traditional Piedmontese architectural style. The building displays characteristic architectural elements typical of the region's religious structures.

A church existed here by 1047, when it is first recorded, then dedicated to Saints Philip and James. It was rebuilt between the 16th and 17th centuries, assigned to the Augustinians in 1643 and consecrated that year. Carlo Ceppi restructured it between the late 19th and early 20th centuries. In 1706 French prisoners who died during the siege of Turin were buried in a well dug inside the church.

The church is on the corner of Via Sant'Agostino and Via Santa Chiara. Its name changed from Saints Philip and James to Augustine of Hippo in 1551, when it was given to the Discalced Augustinians, who also built the adjoining convent. A 15th-century fresco of the Virgin survives on a wall fragment.

The church is easily accessible on foot from Turin's historic center and sits along a main street. Visitors should note that regular services occur, which may affect visiting hours and access at certain times.

In 1706, during the French siege of Turin, French prisoners who died were buried in a well dug inside the church for that purpose. The monument to Cassiano dal Pozzo senior (1498–1578) is by an unknown artist, while the mausoleum of Cardinal Carlo Tommaso Maillard de Tournon is by Carlo Antonio Tantardini.
