Gemonian stairs

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.

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.

Santi Luca e Martina is a church in Rome, Italy, situated between the Roman Forum and the Forum of Caesar and close to the Arch of Septimus Severus.

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.

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 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.

Santi Sergio e Bacco al Foro Romano (Italian: Saints Sergius and Bacchus at the Roman Forum) also called Santi Sergio e Bacco sub Capitolio (Saints Sergius and Bacchus under the Capitoline) was an ancient titular church in Rome, now lost. Located in the ruins of the Roman Forum, it had been one of the ancient diaconiae of the city and a collect church for one of the station days of Lent, but it was demolished in the sixteenth century.

The Arch of Septimius Severus (Italian: Arco di Settimio Severo) at the northeastern end of the Roman Forum is a white marble triumphal arch dedicated in 203 A.D. to commemorate the Parthian victories of Emperor Septimius Severus and his two sons, Caracalla and Geta, in the two campaigns against the Parthians of 194-195 A.D. and 197–199 A.D. After the death of Septimius Severus, his sons Caracalla and Geta were initially joint emperors. Caracalla had Geta assassinated in 212 A.D.; Geta's memorials were destroyed and all images or mentions of him were removed from public buildings and monuments. Accordingly, Geta's image and inscriptions referring to him were removed from the arch.

The Graecostasis was a platform in the Comitium near the Roman Forum, located to the west of the Rostra. The name refers to the Greek ambassadors for whom the platform was originally built after the Roman Republic conquered Greece. Placed at the southwest end of the Comitium, the platform was the designated spot for all representatives of foreign nations and dignitaries from the republic and empire's domain. Visiting outsiders were not permitted within the Senate House or Curia and instead may have stood on this platform while waiting to meet with senators or to hear orations from the Rostra to its east side. Although one scholar has disputed this interpretation and argues that it may have served as a viewing platform for entertainment.

The Curia Hostilia was one of the original senate houses or "curiae" of the Roman Republic. It was believed to have begun as a temple where the warring tribes laid down their arms during the reign of Romulus (r. c. 771–717 BC). During the early monarchy, the temple was used by senators acting as a council to the king. Tullus Hostilius (r. 673–641 BC) was believed to have replaced the original structure after fire destroyed the converted temple. It may have held historic significance as the location of an Etruscan mundus and altar. The Lapis Niger, a series of large black marble slabs, was placed over the altar (known as the Volcanal) where a series of monuments was found opposite the Rostra. This curia was enlarged in 80 BC by Lucius Cornelius Sulla during his renovations of the comitium. That building burned down in 52 BC when the supporters of the murdered Publius Clodius Pulcher used it as a pyre to cremate his body.

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.

The Umbilicus Urbis Romae (Classical Latin: [ʊmbɪˈliːkʊs ˈʊrbɪs ˈroːmae̯])—"Navel of the City of Rome"—was the symbolic centre of the city from which, and to which, all distances in Ancient Rome were measured. It was situated in the Roman Forum where its remnants can still be seen. These remains are located beside the Arch of Septimius Severus and the Vulcanal, behind the Rostra. Originally covered in marble, the Umbilicus is now a forlorn-looking brick core some 2 metres high and 4.45 metres in diameter.
