Porta Fontinalis

The Basilica Argentaria is a portico with pillars lining the Temple of Venus Genetrix in the Forum of Caesar in Rome (Italy). The name only appears in late sources of the age of Constantine. The building was erected under Trajan, with the purpose of adapting the slopes of the Capitoline Hill after the removal of the gap between it and the Quirinal Hill. It was higher than the level of the square and the access was through two staircases on the south-west end of the portico. The portico had two rows of pillars made of tuff stones and its naves were covered with barrel vaults, partially preserved. As the basilica rose in an obligated space, it has an irregular drawing, turning round the temple and probably continuing out of the present archaeological area, close to the south-west exedra of the Trajan's Forum. The plaster covering the back wall of the building, still preserved, displays several graffiti, some of which quote lines of the Aeneid: this detail makes possible that the basilica housed a school, mentioned by late sources about the Trajan's Forum and the Forum of Augustus.

The Temple of Venus Genetrix (Latin: Templum Veneris Genetricis) is a ruined temple in the Forum of Caesar, Rome, dedicated to the Roman goddess Venus Genetrix, the founding goddess of the Julian gens. It was dedicated to the goddess on September 26, 46 BCE by Julius Caesar.

The Forum of Caesar, also known by the Latin Forum Iulium or Forum Julium, Forum Caesaris, was a forum built by Julius Caesar near the Forum Romanum in Rome in 46 BC.

The Mamertine Prison (Italian: Carcere Mamertino), in antiquity the Tullianum, was a prison (carcer) with a dungeon (oubliette) located in the Comitium in ancient Rome. It is said to have been built in the 7th century BC and was situated on the northeastern slope of the Capitoline Hill, facing the Curia and the imperial fora of Nerva, Vespasian, and Augustus. Located between it and the Tabularium (record house) was a flight of stairs leading to the Arx of the Capitoline known as the Gemonian stairs. The church of San Giuseppe dei Falegnami now stands above the Mamertine.

The Gemonian Stairs (Latin: Scalae Gemoniae, Italian: Scale Gemonie) were a flight of steps located in the ancient city of Rome. Nicknamed the Stairs of Mourning, the stairs are infamous in Roman history as a place of execution.

The Basilica Porcia was the first civil basilica built in ancient Rome. It was built by order of Marcus Porcius Cato in 184 BC as censor and is named after him. He built it as a space for administering laws and for merchants to meet, against some opposition. It stood to the west of the Curia, on land bought by Cato and previously occupied by shops and private houses. Many trials were held inside the basilica. It was destroyed by fire after the body of Publius Clodius Pulcher was alit on a pyre in the adjoining senate house in 52 BC. The ruins were probably flattened later that year to build a new building on the site.

San Giuseppe dei Falegnami (Italian, "St. Joseph of the Carpenters"), also called San Giuseppe a Campo Vaccino ("St. Joseph at the Cowfield", an old name for the Roman Forum) is a Roman Catholic church, located in the Forum in Rome, Italy. In 1540, the Congregation of the Carpenters had leased the former church of San Pietro in Carcere which was located over the Mamertine Prison, which by legend had held Saint Peter and Saint Paul. By 1597 work began on the new church, dedicated to the patron saint of Carpenters, St. Joseph. The initial architect was Giacomo della Porta. Work continued after 1602 under the direction of Giovanni Battista Montano, who designed the facade, and at his death (1621) by his pupil Giovanni Battista Soria. The church was completed in 1663 by Antonio Del Grande. The church was restored in 1886 with the construction of a new apse. In the 1930s, the facade was raised above the floor to allow direct access to the prison below. The interior has a nave with two side chapels that were decorated in the nineteenth century. Among the paintings is a Nativity (1651) by Carlo Maratta. Next to the church is an oratory, with a wooden ceiling, and the 16th-century Chapel of the Crucifix, placed between the church floor and the ceiling below the Mamertine Prison. On 18 February 2012, it became a titular church, receiving its first Cardinal-Deacon. On 30 August 2018, there was a partial collapse of the church's roof.

The Temple of Juno Moneta (Latin: Templum Iunonis Monetæ) was an ancient Roman temple that stood on the Arx or the citadel on the Capitoline Hill overlooking the Roman Forum. Located at the center of the city of Rome, it was next to the place where Roman coins were first minted, and probably stored the metal and coins involved in this process, thereby initiating the ancient practice of associating mints with temples. In addition, it was the place where the books of the magistrates were deposited.

The Basilica Opimia was one of four Republican-era basilicas in the Roman Forum. The other two were the Basilica Aemilia, the Basilica Porcia, and the Basilica Sempronia. Of the three, only the Basilica Aemilia partially survives. It was built in 121 BC near the Temple of Concord and named after Lucius Opimius, who had financed its construction and that of the temple. When the Temple of Concord was enlarged under Tiberius the basilica had to be sacrificed and there is no record of its survival after that date.

The Basilica of St. Mary of the Altar of Heaven (Latin: Basilica Sanctae Mariae de Ara coeli in Capitolio, Italian: Basilica di Santa Maria in Ara coeli al Campidoglio) is a titular basilica in Rome, located on the highest summit of the Campidoglio. It is still the designated Church of the city council of Rome, which uses the ancient title of Senatus Populusque Romanus. The present Cardinal Priest of the Titulus Sanctae Mariae de Aracoeli is Salvatore De Giorgi. The shrine is known for housing relics belonging to Saint Helena, mother of Emperor Constantine, various minor relics from the Holy Sepulchre, both the canonically crowned images of Nostra Signora di Mano di Oro di Aracoeli (1636) on the high altar and the Santo Bambino of Aracoeli (1897).

The Columna Maenia was an honorary column erected in the comitium of the Roman Republic by Gaius Maenius in 338 BC for his victory over the Latins at the Battle of Antium. Gaius Maenius also adorned the Rostra, with the naval rams (rostra in Latin) of six ships from the Antiate fleet confiscated by Rome. The column was beside the Rostra and the Graecostasis. Some historians believe the column to be from the atrium of Gaius Maenius's home which was sold to Cato and Flaccus as mentioned by Pseudo-Asconius (Caec. 50).The column was used as part of an elaborate timing device which determined the final hour of the day when the sun was viewed from the Curia Hostilia passing the column, moving towards the Carcer. Pliny states that the accensus consulum announced the supremam horam, the time when the sun had moved downward from the Columna Maenia to the Carcer. This was done from the same location as the call for midday, the Curia. The column was south of the place of observation or on a line which passed from the Rostra and Graecostasis.Various petty criminals were bound to the column as a form of public punishment.

The Temple of Concord (Latin: Aedes Concordiae) in the ancient city of Rome refers to a series of shrines or temples dedicated to the Roman goddess Concordia, and erected at the western end of the Roman Forum. The earliest temple is believed to have been vowed by Marcus Furius Camillus in 367 BC, but it may not have been built until 218 BC by L. Manlius. The temple was rebuilt in 121 BC, and again by the future emperor Tiberius between 7 BC and AD 10.
