Temple of Antoninus and Faustina

The Regia ("Royal house") was a two-part structure in Ancient Rome lying along the Sacra Via at the edge of the Roman Forum that originally served as the residence or one of the main headquarters of kings of Rome and later as the office of the Pontifex Maximus, the highest religious official of Rome. It occupied a triangular patch of terrain between the Temple of Vesta, the Temple of Divus Julius and Temple of Antoninus and Faustina. Only the foundations of Republican/Imperial Regia remain. Like the Curia it was destroyed and rebuilt several times, as far back as the Roman monarchy. Studies have found multiple layers of similar buildings with more regular features, prompting the theory that this "Republican Regia" was to have a different use.

The House of the Vestal Virgins (Latin: Atrium Vestae; Italian: Casa delle Vestali) was the residence of Vestal Virgins, located behind the circular Temple of Vesta at the eastern edge of the Roman Forum, between the Regia and the Palatine Hill. The domus publica, where the Pontifex Maximus dwelled, was located near the Atrium until that role was assumed by the emperors.The Atrium Vestae was a three-story 50-room palace in the ancient Roman Forum built around an elegant elongated atrium or court with a double pool. To the very east is an open vaulted hall with a statue of Numa Pompilius, the mythological founder of the cult. The complex lay at the foot of the Palatine Hill, where a sacred grove that was slowly encroached upon lingered into Imperial times, when all was swept away by the Fire of Rome in 64. The House of the Vestals was rebuilt several times in the course of the Empire. After the dissolution of the College of the Vestals in the late 4th century AD, the House of the Vestals continued to serve as a residence building. It now housed officials of the imperial court, and subsequently the papal court. Archaeological finds from this period include a hoard of 397 gold coins from the 5th century and another 830 Anglo-Saxon coins dating from the 9th and 10th centuries. The site was abandoned in the 11th/12th century. Today, remains of the statues of the Vestals can be seen in the Atrium Vestae.

The Temple of Caesar or Temple of Divus Iulius (Latin: Aedes Divi Iuli; Italian: Tempio del Divo Giulio), also known as Temple of the Deified Julius Caesar, delubrum, heroon or Temple of the Comet Star, is an ancient structure in the Roman Forum of Rome, Italy, located near the Regia and the Temple of Vesta.

The Forum Piscarium (Italian: Foro Piscario) was the fish market of ancient Rome (a forum venalium), north of the Roman Forum, between the Sacra Via and the Argiletum. It was burned in 210 BC and rebuilt the next year. In 179 BC it was incorporated in the general Macellum, built by Marcus Fulvius Nobilior in the same region.This forum is called piscatorium in Livy, and piscarium in Varro and Plautus (Curc. 474).

The Basilica Aemilia (Italian: Basilica Emilia) was a civil basilica in the Roman Forum, in Rome, Italy. Today only the plan and some rebuilt elements can be seen. The Basilica was 100 meters (328 ft) long and about 30 meters (98 ft) wide. Along the sides were two orders of 16 arches, and it was accessed through one of three entrances.

The sacred fire of Vesta was a sacred eternal flame in ancient Rome. The Vestal Virgins, originally numbering two, later four, and eventually six, were selected by lot and served for thirty years, tending the holy fire and performing other rituals connected to domestic life—among them were the ritual sweeping of the temple on June 15 and the preparation of food for certain festivals. By analogy, they also tended the life and soul of the city and of the body politic through the sacred fire of Vesta. The eternal burning of the sacred fire was a sign that determined eternal Rome. The fire was renewed every year on the Kalends of March. Plutarch's (c. 1st century AD) Parallel Lives records the Vestal Virgins use of burning mirrors to relight the fire: If it (the fire) happens by any accident to be put out ... it is not to be lighted again from another fire, but new fire is to be gained by drawing a pure and unpolluted flame from the sunbeams. They kindle it generally with concave vessels of brass, formed by hollowing out an isosceles rectangular triangle, whose lines from the circumference meet in one single point. This being placed against the sun, causes its rays to converge in the centre, which, by reflection, acquiring the force and activity of fire, rarefy the air, and immediately kindle such light and dry matter as they think fit to apply. (tr. Langhorne 1821 1: 195) Allowing the sacred fire to die out was a serious dereliction of duty; it suggested that the goddess had withdrawn her protection from the city. Vestals guilty of this offence were punished by a scourging or a beating.The sacred fire burned in Vesta's circular temple, built in the Roman Forum below the Palatine Hill in pre-republican times. Among other sacred objects in the temple was the Palladium, a statue of Pallas Athena supposedly brought by Aeneas from Troy. The temple burned completely on at least four occasions and caught fire on two others. It was last rebuilt in AD 191 on the orders of Julia Domna, the wife of the emperor Septimius Severus.

The Temple of Vesta, or the aedes (Latin Aedes Vestae; Italian: Tempio di Vesta), is an ancient edifice in Rome, Italy. The temple is located in the Roman Forum near the Regia and the House of the Vestal Virgins. The Temple of Vesta housed Vesta's holy fire, which was a symbol of Rome's safety and prosperity. The temple's most recognizable feature is its circular footprint. Since the worship of Vesta began in private homes, the architecture seems to pay homage to the architecture of early Roman homes. The temple used Greek architecture with Corinthian columns, marble, and had a central cella. The surviving structure indicates that there were twenty Corinthian columns built on a podium fifteen meters in diameter. The roof probably had a vent at the apex to allow smoke to release.

The Temple of Jupiter Stator ("Jupiter the Sustainer") was a sanctuary at the foot of the Palatine Hill in Rome. In Roman legend, it was founded by King Romulus after he pledged to build it during a battle between the Roman army and that of the Sabines. However, no temple was actually built on the site until the early 3rd century BC.

The Arch of Augustus (Italian: Arco di Augusto) was the triumphal arch of Augustus, located in the Roman Forum. It spanned the Via Sacra, between the Temple of Castor and Pollux and the Temple of Caesar, near the Temple of Vesta, closing off the eastern end of the Forum. It can be regarded as the first permanent three-bayed arch ever built in Rome.The archaeological evidence shows the existence of a three-bayed arch measuring 17,75 x 5.25 meters between the Temple of Caesar and the Temple of Castor and Pollux, although only the travertine foundations of the structure remain.Ancient sources mention arches erected in honor of Augustus in the Forum on two occasions: the victory over Antony and Cleopatra in 31 BC, and the recovery of the standards lost to the Parthians in 20 BC.

The basilica of Santi Cosma e Damiano is a titular church in Rome, Italy. The lower portion of the building is accessible through the Roman Forum and incorporates original Roman buildings, but the entrance to the upper level is outside the Forum. The circular building located at the entrance of the Forum, which now houses a small archeological exhibit, was built in the early 4th century as a Roman temple. It is thought to have been dedicated to Valerius Romulus, deified son of the emperor Maxentius. The main building was perhaps the library of an imperial forum. It became a church in 527 and contains important but much restored early Christian art, especially in its mosaics. Today it is one of the ancient churches called tituli, of which cardinals are patrons as cardinal-deacons. Since 28 November 2020 the title has been held by Cardinal Mario Grech. The basilica, devoted to the two Arabian Christian brothers, doctors, martyrs and saints Cosmas and Damian, is located in the Forum of Vespasian, also known as the Forum of Peace.

The Basilica Fulvia was a basilica built in ancient Rome. According to Livy (40.51), the censors M. Aemilius Lepidus and M. Fulvius Nobilior (after whom it was named) had it built in 179 BC. It may be that there had been a previous building existing on the site from 210 BC which was incorporated (Plaut. Capt. 815, Curc. 472). In 78 BC, the consul M. Aemilius Lepidus incorporated the building into the Basilica Aemilia (Plin. Nat. Hist. 35.13), and it was renamed the Basilica Fulvia et Aemilia or sometimes simply the Basilica.

The Lacus Iuturnae — or Lacus Juturnae or Spring of Juturna — is the name of a formal pool built by the Romans near a spring or well in the Roman Forum. The pool was part of a shrine dedicated to the water nymph Juturna, and the name Lacus Iuturnae is also used for the spring and the shrine, both next to the pool.The site was initially excavated by Giacomo Boni in the early twentieth century. Excavations from the 1980s onwards were supervised by Eva Margareta Steinby.
