Temple of Janus (Forum Holitorium)

San Nicola in Carcere (Italian, "St Nicholas in prison") is a titular church in Rome near the Forum Boarium in rione Sant'Angelo. It is one of the traditional stational churches of Lent.

The Forum Holitorium (Italian: Foro Olitorio; English: Vegetable-sellers' Market) is an archaeological area of Rome, Italy, on the slopes of the Capitoline Hill. It was "oddly located" outside the Porta Carmentalis in the Campus Martius, crowded between the Forum Boarium ("Cattle Market") and buildings located in the Circus Flaminius. In ancient times it was the fruit and vegetable market, while the area of the adjacent Forum Boarium served as meat market. It also included a sacred area with three small temples dedicated to Janus, Spes and Juno Sospita.

The Porta Carmentalis was a double gate in the Servian Walls of ancient Rome. It was named for a nearby shrine to the goddess or nymph Carmenta, whose importance in early Roman religion is also indicated by the assignment of one of the fifteen flamines to her cult, and by the archaic festival in her honor, the Carmentalia. The shrine was to the right as one exited the gate. The gate's two arches seem to have been set at angles, and were known by separate names. It was unlucky to leave the city through the arch called Porta Scelerata ("Accursed Gate"), which was supposed to have been named for the military disaster at Cremera in 479 or 478 BC, since the 306 Fabii who died had departed through it. The Servian Walls, however, did not exist at that time. The accursed nature of the gate probably derives from the transport of corpses out of the city proper to funeral pyres on the Campus Martius. The family tomb of the Claudii was located outside the Porta Carmentalis.The other gate was the Porta Triumphalis. A governor returning from his province could not enter through this gate unless he had been awarded a triumph. It therefore must have been routine to use the Porta Scelerata for entering, and the Triumphalis for exiting. Funeral processions reversed the normal direction of traffic flow for the Scelerata, as the triumphal procession did for the Triumphalis. Augustus was accorded the special honor of having his funeral procession exit by the Triumphalis.The temples of Mater Matuta and Fortuna were nearby. The Carmentalis was rebuilt by Domitian, and topped with a sculpture group of a triumphal chariot drawn by elephants. The gate is depicted in relief sculpture dating to the reign of Marcus Aurelius.The Vicus Iugarius forked just before reaching the Porta Carmentalis, with one branch passing through the Forum Holitorium by making a right curve around the foot of the Capitoline Hill, and the other passing through the Forum Boarium to the mouth of the Cloaca Maxima on the Tiber. The precise location of the Porta Carmentalis itself remains unclear, despite excavations in the area from the late 1930s onward. Livy names the Porta Carmentalis as the point of entry for a ritual procession undertaken in 207 BC as part of an expiatory sacrifice for Juno. Two white cows were led from the Temple of Apollo through the Carmentalis and along the Vicus Iugarius to the Forum.

The Theatre of Marcellus (Latin: Theatrum Marcelli, Italian: Teatro di Marcello) is an ancient open-air theatre in Rome, Italy, built in the closing years of the Roman Republic. At the theatre, locals and visitors alike were able to watch performances of drama and song. Today its ancient edifice in the rione of Sant'Angelo, Rome, once again provides one of the city's many popular spectacles or tourist sites. Space for the theatre was cleared by Julius Caesar, who was murdered before its construction could begin; the theatre was advanced enough by 17 BC that part of the celebration of the ludi saeculares took place within the theatre; it was completed in 13 BC and formally inaugurated in 12 BC by Augustus, named after his nephew Marcus Claudius Marcellus who had died in 23 BC. The theatre was 111 m in diameter and was the largest and most important theatre in Ancient Rome; it could originally hold between 11,000 and 20,000 spectators. A catalogue complied at the end of the 4th century recorded that the theatre's seating capacity was 17,580 persons. It was an impressive example of what was to become one of the most pervasive urban architectural forms of the Roman world. The theatre was built mainly of tuff, and concrete faced with stones in the pattern known as opus reticulatum, completely sheathed in white travertine. However, it is also the earliest dateable building in Rome to make use of fired Roman brick, then a new introduction from the Greek world.The network of arches, corridors, tunnels and ramps that gave access to the interiors of such Roman theatres were normally ornamented with a screen of engaged columns in Greek orders: Doric at the base, Ionic in the middle. It is believed that Corinthian columns were used for the upper level but this is uncertain as the theatre was reconstructed in the Middle Ages, removing the top tier of seating and the columns.Like other Roman theatres in suitable locations, it had openings through which the natural setting could be seen, in this case the Tiber Island to the southwest. The permanent setting, the scaena, also rose to the top of the cavea as in other Roman theatres. The theatre fell out of use in the early 4th century and the structure served as a quarry, e.g., for the Pons Cestius in 370 AD. However, the statues located inside the building were restored by Petronius Maximus in 421 and the remaining structure still housed small residential buildings. In the Early Middle Ages the theatre was used as a fortress of the roman family of Faffo or Fabi (called "from Pescheria") and then at the end of the 11th century (when it was known as templum Marcelli), by Pier Leoni and later his heirs (the Pierleoni). This saved the complex from further destruction. The Savelli held it in the 13th century. Later, in the 16th century, the residence of the Orsini, designed by Baldassare Peruzzi, was built atop the ruins of the ancient theatre. By the 19th century, rises in the street level meant that almost half the ground floor was below it. Now the upper floors are divided into multiple apartments, and its surroundings are used as a venue for small summer concerts; the Portico d'Ottavia lies to the north west leading to the Roman Ghetto and the Tiber to the south west. In the 17th century, the English architect Sir Christopher Wren explicitly acknowledged that his design for the Sheldonian Theatre in Oxford was influenced by Serlio's engraving of the Theatre of Marcellus.

Sant'Omobono is a church in Rome at the foot of the Capitoline Hill in rione Ripa. It was built in the 15th century and called San Salvatore in Portico. When the church was given to the "Università dei Sarti" (the association of tailors) in 1575, the church was dedicated to their patron saint, Saint Homobonus. Next to it is the Sant'Omobono Area, containing the remains of two Roman temples.

The temple of Bellona was an ancient Roman temple dedicated to the goddess Bellona and sited next to the Temple of Apollo Sosianus and the Theatre of Marcellus in Rome.

The Temple of Fides (Latin: aedes Fidei) was a minor temple on the Capitoline Hill in Rome. It was dedicated to Fides, the goddess of good faith, who was patron of diplomatic relations. The temple was founded between 254 BC or 250 BC. It was on the southern part of the Area Capitolina, slightly to the south of the Temple of Ops, in a vast piazza in front of the Temple of Jupiter Optimus Maximus. If still in use by the 4th-century, it would have been closed during the persecution of pagans in the late Roman Empire. Remains found near the church of Sant'Omobono (including fragments of columns, part of a cement podium and a large female marble head, probably from a temple's acroterion) were previously identified as fragments of the Temple of Ops, but are now thought to be linked to the Temple of Faith, due to the nearby discovery of bilingual inscriptions in Greek and Latin and fragments of treaties between Asia Minor and the Roman Senate.

San Gregorio della Divina Pietà is a small Roman Catholic church facing the Piazza Gerusalemme located in Rione Sant'Angelo, in Rome, Italy. It is located near the Great Synagogue of Rome and the former Jewish quarter of Rome. It is sometimes referred to as San Gregorietto due to its small size. In the past, it was also called San Gregorio a Ponte Quattro Capi or Pons Judaeorum due to its proximity to the bridge known now as Pons Fabricius, connecting the sector to the Tiber island.

The Chiesa di Santa Rita da Cascia in Campitelli is a deconsecrated church in Rome (Italy), in the rione Sant'Angelo; it is located in Via Montanara, at the crossroad with Via del Teatro Marcello. The church formerly rose on the preexisting church of San Biagio de Mercato, dating at least to the 11th-century. The remains of St Blaise putatively were discovered during the dismantling of Santa Rita.

The Sack of Rome on 24 August 410 AD was undertaken by the Visigoths led by their king, Alaric. At that time, Rome was no longer the capital of the Western Roman Empire, having been replaced in that position first by Mediolanum in 286 and then by Ravenna in 402. Nevertheless, the city of Rome retained a paramount position as "the eternal city" and a spiritual center of the Empire. This was the first time in almost 800 years that Rome had fallen to a foreign enemy, and the sack was a major shock to contemporaries, friends and foes of the Empire alike. The sacking of 410 is seen as a major landmark in the fall of the Western Roman Empire. St. Jerome, living in Bethlehem at the time, wrote; "the city which had taken the whole world was itself taken."

The main road to the Roman Capitol, the Clivus Capitolinus ("Capitoline Rise") starts at the head of the Roman Forum beside the Arch of Tiberius as a continuation of the Via Sacra; proceeding around the Temple of Saturn and turning to the south in front of the Portico Dii Consentes, it then climbs up the slope of the Capitoline Hill to the Temple of Jupiter Optimus Maximus at its summit. This was traditionally the last and culminating portion of all Roman triumphs.

The Sant'Omobono Area (Italian: Area di Sant'Omobono) is an archaeological site in Rome next to the church of Sant'Omobono, at the junction of via L. Petroselli and il Vico Jugario at the foot of the Campidoglio. It was discovered in 1937 and contains much important evidence for archaic and republican Rome. It contains altars and the sites of the temple of Fortuna and the temple of Mater Matuta. The temples and their sanctuaries lie between the Forum Holitorium and the Forum Boarium. As of 2012, the archaeological site is under re-investigation by a joint team from the Sovraintendenza ai Beni Culturali of the Comune di Roma, the Università della Calabria, and the University of Michigan.The site of Sant'Omobono is crucial for understanding the related processes of monumentalization, urbanization, and state formation in Rome in the late Archaic period. The Sant'Omobono temple site dates to 7th–6th century BCE, making this pair the oldest known temple remains in Rome.
