Santa Maria in Publicolis

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 Fontana del Pianto, also known as the Fontana di piazza delle Cinque Scole, is a monumental fountain located in the Piazza delle Cinque Scole in the rione of Regola in Rome. The fountain presently takes its name from the church of Santa Maria del Pianto, whose southern entrance is located a few yards north. The fountain was moved here in 1930 under Pope Pius XI, from its prior location inside the former Roman Ghetto. It was located a few more yards north, near the northern entrance to the church of Santa Maria del Pianto. The design of the marble fountain was commissioned by Pope Gregory XIII and is attributed to Giacomo della Porta, and completed by Pietro Gucci circa 1591–1593. It consists of a superior and lower basins with mascarons as spouts. The prior location, where the Via Santa Maria del Pianto becomes Via del Portico d'Ottavia, is marked in the street with white bricks. The fountain shares features, such as mascarons and simple basins with another of Della Porta's fountains: the Fontana di Piazza d'Aracoeli.

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).

Palazzo Costaguti, also known as Palazzo Patrizi Costaguti, is a mannerist architecture Roman, located at the corner of Piazza Mattei with Via della Reginella, in rione Sant’Angelo in Rome. Large in size, it also runs along Via dei Falegnami and its rear facades are in Piazza Costaguti. Currently used as the seat of the Universitas Telematica Mercatorum.

The Fontana delle Tartarughe (The Turtle Fountain) is a fountain of the late Italian Renaissance, located in Piazza Mattei, in the Sant'Angelo district of Rome, Italy. It was built between 1580 and 1588 by the architect Giacomo della Porta and the sculptor Taddeo Landini. The bronze turtles around the upper basin, usually attributed either to Gian Lorenzo Bernini or Andrea Sacchi, were added in either 1658 or 1659 when the fountain was restored.

The Temple of Mars (Latin: Aedes Martis in Circo) was a temple built on the campus Martius in Rome in the 2nd century BC, near the Circus Flaminius, dedicated to Mars. The consul Decimus Junius Brutus Callaicus vowed a temple to Mars in 138 BC and construction began after 135 BC, financed by booty from his campaign in Hispania. It was designed by Hermodorus of Salamis and was dedicated in 132 BC during Junius' triumph. It was restored in the late Republic, retaining its original plan and features. If still in use by the 4th-century, the temple would have been closed during the persecution of pagans in the late Roman Empire, when the Christian Emperors issued edicts prohibiting non-Christian worship.

The Circus Flaminius was a large, circular area in ancient Rome, located in the southern end of the Campus Martius near the Tiber River. It contained a small race-track used for obscure games, and various other buildings and monuments. It was "built", or sectioned off, by Gaius Flaminius in 221 BC. After Augustus divided the city into 14 administrative regions, the Circus Flaminius gave its name to Regio IX, which encompassed the Circus and all of the Campus Martius west of the Via Lata.

Sant'Angelo is the 11th rione of Rome, Italy, located in Municipio I. Often written as rione XI - Sant'Angelo, it has a coat of arms with an angel on a red background, holding a palm branch in its left hand. In another version, the angel holds a sword in its right hand and a scale in its left.Sant'Angelo, the smallest of Rome's rioni, lies along the Tiber river east of Tiber Island. Rioni bordering this district, clockwise from north to south, include Regola, Sant'Eustachio, Pigna, Campitelli, and Ripa. Sant'Angelo's western border is the river. The rione's terrain is low and flat and, until the construction of the Lungotevere, particularly susceptible to flooding from the river. The historical significance of Sant'Angelo is mainly the result of the presence here of the Roman Ghetto.

Largo di Torre Argentina is a square in Rome, Italy, with four Roman Republican temples and the remains of Pompey's Theatre. It is in the ancient Campus Martius.The name of the square comes from the Torre Argentina, which takes its name from the city of Strasbourg whose Latin name was Argentoratum. In 1503, the Papal Master of Ceremonies Johannes Burckardt, who came from Strasbourg and was known as "Argentinus", built in via del Sudario a palace (now at number 44), called Casa del Burcardo, to which the tower is annexed. Julius Caesar was assassinated in the Curia of Pompey, and the spot where he is believed to have been assassinated is in the square.After Italian unification, it was decided to reconstruct part of Rome (1909), demolishing the zone of Torre Argentina. However, during the demolition work in 1927, the colossal head and arms of a marble statue were discovered. The archaeological investigation brought to light the presence of a holy area, dating to the Republican era, with four temples and part of Pompey's Theatre. In 2019, Rome's mayor Virginia Raggi announced that walkways would be installed in the site allowing the general public to tour the ruins for the first time.

Julius Caesar, the Roman dictator, was assassinated by a group of senators on the Ides of March (15 March) of 44 BC during a meeting of the Senate at the Curia of Pompey of the Theatre of Pompey in Rome. The senators stabbed Caesar 23 times. They claimed to be acting over fears that Caesar's unprecedented concentration of power during his dictatorship was undermining the Roman Republic, and presented the deed as an act of tyrannicide. At least 60 senators were party to the conspiracy, led by Marcus Junius Brutus and Gaius Cassius Longinus. Despite the death of Caesar, the conspirators were unable to restore the institutions of the Republic. The ramifications of the assassination led to the Liberators' civil war and ultimately to the Principate period of the Roman Empire.

The Teatro Argentina ( which directly translates into theatre Argentina) is an opera house and theatre located in Largo di Torre Argentina, a square in Rome, Italy. One of the oldest theatres in Rome, it was constructed in 1731 and inaugurated on 31 January 1732 with Berenice by Domenico Sarro. It is built over part of the curia section of the Theatre of Pompey. This curia was the location of the assassination of Julius Caesar.

Theatre of Balbus was an ancient Roman structure in the Campus Martius of Rome. It was built in 13 BC by proconsul Lucius Cornelius Balbus (minor), likely from the spoils of a military campaign by order of Augustus (Cassius Dio 54.18.2; Pliny the Elder, Natural History (Pliny) 36.59-60). Very little is mentioned of the theatre in ancient writings. Its location was debated for decades until pieces of the Forma Urbis were finally pieced together in the 1960s. Excavations of the theatre began in 1981 and are still ongoing, however, the main portion of the crypta finished in 2000. Today what has been excavated can be seen at the Museo Nazionale Romano Crypta Balbi (National Museum of Rome), which is located at Via delle Botteghe Oscure, 31, (corner of Via M. Caetani). The museum is located in what was the crypta or courtyard in the rear of the theater's complex behind the stage. This courtyard was the smallest of all of Rome's major theatres. Here patrons would stroll between acts of a performance and seek refreshment. A catalogue complied at the end of the 4th century recorded that the theatre's seating capacity was 11,510 persons.
