San Carlo ai Catinari

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.

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.

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.

Iuliani Flandrensium) is a Roman Catholic church dedicated to Saint Julian the Hospitaller, located in Rome, Italy. Historically, the church has been the National Church in Rome of the Southern Netherlands and, in 1830, became the national church of the Kingdom of Belgium. According to tradition, the church was built when Flanders converted to the Christian faith, during the pontificate of Gregory II (715–753). The little church is part of a Roman building that was once the hospice of St. Julian of the Flemings, built to shelter pilgrims from the county of Flanders (Belgium). Its official denomination since 1979 is "Royal Belgian church and Foundation of Saint Julian of the Flemings" (Dutch: Koninklijke Belgische kerk en stichting Sint-Juliaan der Vlamingen, French: Eglise et fondation royale belge Saint Julien des Flamands). In the Consistory of November 26, 1994, Jan Pieter Schotte was appointed the first Cardinal-Deacon of St. Julian, a position now occupied by Cardinal Walter Brandmüller, created in 2010.
