Sant'Agostino, Renaissance church in central Cagliari, Italy

Sant'Agostino is a church with a Greek-cross layout located in central Cagliari. The interior is defined by barrel vaults, with a semi-spherical dome rising above the central space.

A 15th-century Gothic church and Eremitani convent stood outside the Marina walls on the spot where Saint Augustine's body was believed kept before its transfer to Pavia in 725. Philip II of Spain had them demolished in 1576 during the strengthening of Cagliari's walls and financed a new church intra moenia, on the site of the Pisan-origin San Leonardo. The Ticino architects Jacopo and Giorgio Palearo Fratino built it with its convent between 1577 and 1580.

The wooden statue of Saint Augustine in the transept is attributed to the Neapolitan sculptor Aniello Stellato and dates to the first quarter of the 17th century; it was restored in 2021. Its gilded, damascened robe is probably the work of the Neapolitan gilder Giuseppe De Rosa, a collaborator of the sculptor.

Visitors can enter through two different points: the main entrance or via the sacristy on Largo Carlo Felice. The interior layout is straightforward and easy to walk through.

Under the left arm of the transept, archaeological excavations revealed the remains of Roman and early medieval buildings beneath the floor. The church also keeps a wooden statue of Saint Augustine attributed to the Neapolitan sculptor Aniello Stellato, dating from the first quarter of the 17th century and restored in 2021.
