San Salvatore in Campo

Santa Maria in Monticelli is a church in the rione of Regola in Rome, sited on the street of the same name. A church was founded at the site in the 12th century and reconsecrated by Innocent II in 1143. It was known as Sancta Maria in Monticellis Arenulae de Urbe, in a bull by Urban IV in 1264. Little remains of the medieval church, except for the bell-tower. The church was entirely reconstructed in 1716 by Matteo Sassi, on a commission by Clement XI, and in 1860 by Francesco Azzurri. The church is the home to the Curia Generalizia dei Padri Dottrinari. The church contains a baroque fresco of the Flagellation attributed to Antonio Carracci; a 13th-century painted wooden crucifix attributed to Pietro Cavallini; a Madonna and child with saints by Sebastiano Conca; and a Head of the Redeemer in mosaic fragments of the 12th century. Near the sanctuary of the church is the contemporary shrine of Blessed César de Bus, the French founder of the "Priests of Christian Doctrine" and the patron saint of catechists.

The Temple of Neptune (Latin: Aedes Neptuni) was an ancient Roman temple dedicated to Neptune on the Campus Martius near the Circus Flaminius in Rome.

The Altar of Domitius Ahenobarbus (more properly called the Statuary group base of Domitius Ahenobarbus) is a series of four sculpted marble plaques that probably decorated a base supporting cult statues in the cella of a Temple of Neptune located in Rome on the Field of Mars. The frieze is dated to the end of the second century BC, which makes it the second oldest Roman bas-relief currently known. However, there is also a contemporaneous relief depicting a Roman naval bireme with armed marines, from a temple of Palestrina built c. 120 BC.The sculpted panels are still visible today, with one portion on display at the Louvre (Ma 975) and another at the Glyptothek in Munich (Inv. 239). A copy of this second piece can be seen at the Pushkin Museum in Moscow.

Palazzo Barberini ai Giubbonari, also called Casa Grande Barberini, to distinguish it from the more famous palace in the Trevi district, is a historic palace in Rome. It was the family's first residence in the papal capital and, even after the construction of the palace at the Quattro Fontane, it remained the home of Taddeo, prince of Palestrina, until he fled to France. The palace remained the property of the Barberini family until the fourth decade of the eighteenth century, when they sold it to the Discalced Carmelites, who made it the seat of their General Curia; later passed to the Monte di Pietà, it is now owned by the municipality of Rome and home to educational institutions, including the Vittoria Colonna High School.

The Porticus of Pompey (known under various names, including the Ambulatio Magni and Hecatostylon or "Hall of a hundred pillars") was a large quadriporticus located directly behind the scaenae frons of the Theatre of Pompey. It enclosed a large and popular public garden in the ancient city of Rome. The porticus was finished in 62 BC. and has a history spanning hundreds of years. The colonnades contained arcades and gallaries that displayed sculptures and paintings collected from years of war campaigns of its patron and builder, Gnaeus Pompeius Magnus. Over time the site became rows of shops that occupied what were the galleries and arcades. As the ground level rose from constant flooding from the Tiber River, much of the original architectural elements were re-used by shop owners to adhorn their structures at higher levels. Today, many of these shops still exist and fragments of the old theatre and porticus can be seen embedded in the ancient walls of many of the buildings.

The Curia of Pompey, sometimes referred to as the Curia Pompeia, was one of several named meeting halls from Republican Rome of historic significance. A curia was a designated structure for meetings of the senate. The Curia of Pompey was located at the entrance to the Theater of Pompey. While the main senate house was being moved from the Curia Cornelia to a new Curia Julia, the senate would meet in this smaller building. It is best known as where members of the Roman Senate murdered Gaius Julius Caesar.The Curia was attached to the porticus directly behind the theatre section and was a Roman exedra, with a curved back wall and several levels of seating. In A New Topographical Dictionary of Ancient Rome by L. Richardson, Jr., Richardson states that after Caesar's murder, Augustus Caesar removed the large statue of Pompey and had the hall walled up. Richardson cited Suetonius that it was later made into a latrine, as stated by Cassius Dio.

The Theatre of Pompey (Latin: Theatrum Pompeii, Italian: Teatro di Pompeo) was a structure in Ancient Rome built during the latter part of the Roman Republican era by Pompey the Great (Gnaeus Pompeius Magnus). Completed in 55 BC, it was the first permanent theatre to be built in Rome. Its ruins are located at Largo di Torre Argentina. Enclosed by the large columned porticos was an expansive garden complex of fountains and statues. Along the stretch of the covered arcade were rooms dedicated to the exposition of art and other works collected by Pompey during his campaigns. On the opposite end of the garden complex was the Curia of Pompey for political meetings. The senate would often use this building along with a number of temples and halls that satisfied the requirements for their formal meetings. The curia is infamous as the place where Julius Caesar was assassinated by Brutus and Cassius during a session of the Senate on 15 March 44 BC.

San Carlo ai Catinari, also called Santi Biagio e Carlo ai Catinari ("Saints Blaise and Charles at the Bowl-Makers") is an early-Baroque style church in Rome, Italy. It is located on Piazza Benedetto Cairoli, 117 just off the corner of Via Arenula and Via dei Falegnami, a few blocks south of the church of Sant'Andrea della Valle. The attribute ai Catinari refers to the presence, at the time of its construction, of the many makers of wooden basins (Italian catini) who worked in the area. The church was commissioned by the Order of the Barnabites and funded by the Milanese community in Rome to honour their fellow Milanese St. Charles Borromeo (Italian: San Carlo). It is one of at least three Roman churches dedicated to him, including San Carlo al Corso and San Carlo alle Quattro Fontane (San Carlino).

The Porticus Octavia (Octavian Portico) was a portico in ancient Rome, built by Gnaeus Octavius in 168 BC to commemorate a naval victory over Perseus of Macedonia. It stood between the Theatre of Pompey and the Circus Flaminius. Pliny describes it as a double portico with bronze Corinthian capitals, for which it was also called the Porticus Corinthia. It may have been the earliest use of this architectural order in Rome, and is possibly to be identified with remains in the Via S. Nicola ai Cesarini, represented in the Severan Marble Plan (frg. 140). Velleius Paterculus called it multo amoenissima, or "by far the loveliest" of the porticoes, but has left no traces.In 33 BC, Octavian (the future Augustus) recovered the military standards lost by Gabinius to the Illyrians, and displayed them at the Porticus Octavia, which he rebuilt to commemorate the conquest of Dalmatia.
