Sant'Agostino is an Augustinian church in Rome, not far from Piazza Navona. It is one of the first Roman churches built during the Renaissance.
For reference, a plan of the church is available here
Sant'Agostino was founded in 1286, when the Roman nobleman Egidio Lufredi donated some houses in the area to the Augustinians. They were asked to erect a church and a convent on the site, and after gaining the consent of Pope Honorius IV (1285-1287), they were built.
The church was rebuilt on a larger scale in the same century, during the pontificate of Sixtus IV (1471-1484). Funding was arranged by Guillaume Cardinal d'Estouteville, who was the papal Camerlengo (chamberlain) and protector of the Augustinian Order. The design was entrusted to the architects Giacomo di Pietrasanta and Sebastiano Fiorentino.
Construction began in 1479, and was finished in 1483, the year that Cardinal d'Estouteville died.
In the 16th century, a lot of work was done in the interior. In 1660 more work was carried out. The plan as it is today is a result of the work done in that period.
Another restoration was carried out under Pope Pius IX (1846-1878); it was completed in 1870. The floor was renewed, pillars were encased in marble and frescoes were added in the nave, transept, choir and in the chapels. The most recent work was carried out in 1998-2000 by the Soprintendenze di Roma per i Beni Ambientali ed Architettonici e per i Beni Artistici e Storici.
