The Basilica of St. Augustine in Campo Marzio (Italian: Basilica di Sant'Agostino in Campo Marzio; Latin: Basilica Sancti Augustini in Campo Martio), commonly known as Basilica of St. Augustine and locally as Sant'Agostino, is a Roman Catholic titular minor basilica dedicated to Saint Augustine of Hippo in Rome, Italy. It is the mother church of the Order of Saint Augustine and it is located near the Piazza Navona in the rione Sant'Eustachio. First conceived in 1286, where a primitive 8th-century church dedicated to St. Tryphon of Campsada was located, the basilica is known for its roman renaissance architecture style, artwork by artists such as Caravaggio, Raphael, Guercino and Bernini, and for being the burial place of Saint Monica (d. 387), mother of Saint Augustine of Hippo.

Two Angels in Sant'Agostino are two marble sculptures above the high altar of the Basilica of Sant'Agostino in Rome. They are listed as being by the Italian artist Gian Lorenzo Bernini in the biography of Baldinucci, and there is also recorded evidence of Bernini having been paid for them. However, it seems likely that Bernini passed the work over to one of his assistants, Giuliano Finelli.One of the bozzetti (preparatory works in terracotta) is in the Ringling Museum, Sarasota, in the USA. It was verified as a Bernini by art historian Rudolf Wittkower and purchased for US$5,880 by the museum in 1961; a fact corroborated in newspaper reports of the time. However, the current Ringling museum website states the work to be the design of Bernini and executed by Giuliano Finelli.

Pontifical University of the Holy Cross (Latin: Pontificia Universitas Sanctae Crucis, Italian: Pontificia Università della Santa Croce) is a Roman Catholic university under the Curial Congregation for Catholic Education, now entrusted to the Prelature of the Holy Cross and Opus Dei, or more commonly called Opus Dei.

One is in Piazza di Sant'Apollinare, northern area of Piazza Navona; another (the library) is Via dei Farnesi near the famous Palazzo Farnese. Its stated mission is "to serve the whole Church by means of a broad and thorough work of research and formation in the ecclesiastical sciences, cooperating according to its special function with the evangelizing mission of the Church in the whole world."

The Ludovisi Battle sarcophagus or "Great" Ludovisi sarcophagus is an ancient Roman sarcophagus dating to around AD 250–260, found in 1621 in the Vigna Bernusconi, a tomb near the Porta Tiburtina. It is also known as the Via Tiburtina Sarcophagus, though other sarcophagi have been found there. It is known for its densely populated, anti-classical composition of "writhing and highly emotive" Romans and Goths, and is an example of the battle scenes favored in Roman art during the Crisis of the Third Century. Discovered in 1621 and named for its first modern owner, Ludovico Ludovisi, the sarcophagus is now displayed at the Palazzo Altemps in Rome, part of the National Museum of Rome as of 1901.The sarcophagus is a late outlier in a group of about twenty-five late Roman battle sarcophagi, the others all apparently dating to 170–210, made in Rome or in some cases Athens. These derive from Hellenistic monuments from Pergamon in Asia Minor showing Pergamene victories over the Gauls, and were all presumably commissioned for military commanders. The Portonaccio sarcophagus is the best known and most elaborate of the main Antonine group and shows both considerable similarities to the Great Ludovisi sarcophagus, and a considerable contrast in style and mood.
