Sant'Agostino is a Roman Catholic church in the piazza of the same name near Piazza Navona, in the rione Sant'Eustachio, of Rome, Italy. It is one of the first Roman churches built during the Renaissance. The construction was funded by Guillaume d'Estouteville, Archbishop of Rouen and Papal Chancellor. The façade was built in 1483 byGiacomo di Pietrasanta, using travertine taken from the Colosseum. The design of the church is attributed to the late 15th century architect Baccio Pintelli, with later 18th century restorations by Luigi Vanvitelli. It is a plain work of the early Renaissance style.
