Palazzo di Sant'Apollinare

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. It was started in 1984 by Opus Dei, with the aim of offering the universal church an effective instrument for formation and research. Located in the heart of Rome, it has two campuses. 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." Pope John Paul II granted the title of 'university' to the Pontifical Atheneum of the Holy Cross in July 1998, making it the sixth pontifical university in the city of Rome. The University is open to lay people, both men and women, priests, seminarians, and religious brothers and sisters.

The Basilica di Sant'Apollinare alle Terme Neroniane-Alessandrine ("Basilica of Saint Apollinaris at the Baths of Nero") is a titular church in Rome, Italy, dedicated to St Apollinare, the first bishop of Ravenna. It is the station church for the Thursday of the fifth week in Lent.

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.

The Tor Sanguigna is one of the medieval towers of Rome, Italy, built of tufa blocks and brick sited a few metres from piazza Navona in that city's Ponte district. 'Tor Sanguigna' was already used in the Middle Ages as a toponym for the whole surrounding area between what are now via Zanardelli, via dei Coronari and Sant'Agostino church. The piazza in which the tower stands is now named after it.

Olav Trondsson (died November 25, 1474) was the twenty-fourth Catholic archbishop of the Archdiocese of Nidaros in Norway from 1459 until his death in 1474.

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.

The Fountain of Neptune (Italian: Fontana del Nettuno) is a fountain in Rome, Italy, located at the north end of the Piazza Navona. It was once called "Fontana dei Calderari" because it was located close to a small alley with blacksmith's workshops, makers of pots and pans and of other metal based businesses, all of them generating heat. The restoration of the Roman Aqua Virgo aqueduct in 1570 was immediately followed by the start of work on a continuation water supply pipe towards the district of the old Campo Marzio, which following the diminution of the city's size and importance was left as the most densely populated part of the city. Restoration of a piped water supply in turn permitted the construction of several public fountains. The basin of the Fontana del Nettuno, (without the sculptures), was designed in 1574 by Giacomo Della Porta, who was also responsible for the Moor Fountain at the other side of the square. It was sponsored by pope Gregory XIII. The lower part of the basin consists of white marble and the upper part of the local stone from Pietrasanta. For the next 300 years, the fountain survived without statues. Nineteenth-century infrastructure developments reduced dependence on urban fountains for drinking and washing purposes but increased their visual and political importance, especially following the creation of the Italian state with Rome as its capital after 1870. The fountain as it exists today was finally completed in 1878 by Antonio della Bitta, who added the imposing sculpture of Neptune fighting with an octopus, and Gregorio Zappalà, who created the other sculptures, based on the mythological theme of the "Nereids with Cupids and walruses". This statuary was added following a competition in 1873, in order to balance that of the Moor Fountain on the south side of the piazza and of the Fontana dei Quattro Fiumi (Fountain of the Four Rivers) at its centre.
