Santi Luca e Martina

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 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 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 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 Comitium (Italian: Comizio) was the original open-air public meeting space of Ancient Rome, and had major religious and prophetic significance. The name comes from the Latin word for "assembly". The Comitium location at the northwest corner of the Roman Forum was later lost in the city's growth and development, but was rediscovered and excavated by archaeologists at the turn of the twentieth century. Some of Rome's earliest monuments; including the speaking platform known as the Rostra, the Columna Maenia, the Graecostasis and the Tabula Valeria were part of or associated with the Comitium. The Comitium was the location for much of the political and judicial activity of Rome. It was the meeting place of the Curiate Assembly, the earliest Popular assembly of organised voting divisions of the Republic. Later, during the Roman Republic, the Tribal Assembly and Plebeian Assembly met there. The Comitium was in front of the meeting house of the Roman Senate – the still-existing Curia Julia and its predecessor, the Curia Hostilia. The Curia Julia is associated with the Comitium by both Livy and Cicero.Most Roman cities had a similar comitium for public meetings (L. contiones) or assemblies for election], councils and tribunals. As part of the forum, where temples, commerce, judicial, and city buildings were located, the comitium was the center of political activity. Romans tended to organize their needs into specific locations within the city. As the city grew, the larger Comitia Centuriata met on the Campus Martius, outside the city walls. The comitium remained of importance for formal elections of some magistrates; however, as their importance decayed after the end of the republic, so did the importance of the comitium.

Sant'Adriano al Foro was a church in Rome, formerly in the Curia Julia in the Forum Romanum and a cardinal-deaconry (a titular church for a Cardinal-deacon).

The Curia Julia (Latin: Curia Iulia, Italian: Curia Iulia) is the third named curia, or senate house, in the ancient city of Rome. It was built in 44 BC, when Julius Caesar replaced Faustus Cornelius Sulla's reconstructed Curia Cornelia, which itself had replaced the Curia Hostilia. Caesar did so to redesign both spaces within the Comitium and the Roman Forum. The alterations within the Comitium reduced the prominence of the Senate and cleared the original space. The work, however, was interrupted by Caesar's assassination at the Curia of Pompey of the Theatre of Pompey, where the Senate had been meeting temporarily while the work was completed. The project was eventually finished by Caesar's successor, Augustus Caesar, in 29 BC.The Curia Julia is one of a handful of Roman structures that survive mostly intact. This is due to its conversion into the basilica of Sant'Adriano al Foro in the 7th century and several later restorations. However, the roof, the upper elevations of the side walls and the rear façade are modern and date from the remodeling of the deconsecrated church, in the 1930s.

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 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.

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 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.

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.
