Basilica Opimia

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.

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 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 altar of Saturn (Latin: Ara Saturni) is an archaic altar dedicated to the god Saturn. Constructed in the sixth century BCE, it continued to be used until the Roman Empire collapsed. It is located in front of the Temple of Saturn in the Roman Forum and its remains were uncovered by Rodolfo Lanciani in 1902.

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 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.

The Shrine of Vulcan (Italian: Volcanale), or Vulcanal, or Volcanal, was an 8th-century BC sacred precinct on the future site of the Roman Forum in Rome, modern Italy. Dedicated to Vulcan, the Roman god of fire, it was traditionally considered to commemorate the spot where the legendary figures Romulus and Tatius concluded the peace treaty between the tribes known as the Latins — on the Palatine Hill — and the Sabines — on the Quirinal and Esquiline. This famous merger of the hill-villages was said to be the foundation of the Roman state.

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 rostra (Italian: Rostri) was a large platform built in the city of Rome that stood during the republican and imperial periods. Speakers would stand on the rostra and face the north side of the comitium towards the senate house and deliver orations to those assembled in between. It is often referred to as a suggestus or tribunal, the first form of which dates back to the Roman Kingdom, the Vulcanal.It derives its name from the six rostra (plural of rostrum, a warship's ram) which were captured following the victory which ended the Latin War in the Battle of Antium in 338 BC and mounted to its side. Originally, the term meant a single structure located within the Comitium space near the Forum and usually associated with the Senate Curia. It began to be referred to as the Rostra Vetera ("Elder Rostra") in the imperial age to distinguish it from other later platforms designed for similar purposes which took the name "Rostra" along with its builder's name or the person it honored.

The Five-Columns monument is a dedicatory addition to the Rostra in the Roman Forum dating to the early fourth century CE. This monument was part of the Tetrarchy’s expansion of the Forum and is connected to the tenth anniversary of the Caesares within the four-ruler system. It is also referred to as the Fünfsäulendenkmal as well as the four-column monument, depending on Jupiter’s inclusion.

The Temple of Vespasian and Titus (Latin: Templum divi Vespasiani, Italian: Tempio di Vespasiano) is located in Rome at the western end of the Roman Forum between the Temple of Concordia and the Temple of Saturn. It is dedicated to the deified Vespasian and his son, the deified Titus. It was begun by Titus in 79 after Vespasian's death and Titus's succession. Titus’ brother, Domitian, completed and dedicated the temple to Titus and Vespasian in approximately 87.

The Plutei of Trajan (Latin Plutei Traiani; often called the Anaglypha Traiani) are carved stone balustrades built for the Roman emperor Trajan. They are on display inside the Curia Julia in the Forum Romanum today, but are not part of the original structure. It is unknown exactly where Trajan erected them. They are believed to have been built either on the edge of the Rostra or on the sides of the black pavement marking the underground "Tomb of Romulus". In spite of this uncertainty, they are of great historical value because the carvings show the full length of both sides of the Forum at the time they were erected.
