Palazzo Mattei

Theatre of Balbus was an ancient Roman structure in the Campus Martius of Rome. It was built in 13 BC by proconsul Lucius Cornelius Balbus (minor), likely from the spoils of a military campaign by order of Augustus (Cassius Dio 54.18.2; Pliny the Elder, Natural History (Pliny) 36.59-60). Very little is mentioned of the theatre in ancient writings. Its location was debated for decades until pieces of the Forma Urbis were finally pieced together in the 1960s. Excavations of the theatre began in 1981 and are still ongoing, however, the main portion of the crypta finished in 2000. Today what has been excavated can be seen at the Museo Nazionale Romano Crypta Balbi (National Museum of Rome), which is located at Via delle Botteghe Oscure, 31, (corner of Via M. Caetani). The museum is located in what was the crypta or courtyard in the rear of the theater's complex behind the stage. This courtyard was the smallest of all of Rome's major theatres. Here patrons would stroll between acts of a performance and seek refreshment. A catalogue complied at the end of the 4th century recorded that the theatre's seating capacity was 11,510 persons.

It was built between 1580 and 1588 by the architect Giacomo della Porta and the sculptor Taddeo Landini.

The Palazzo Caetani, also known as the Palazzo Mattei Caetani, and once known as the Palazzo of Alessandro Mattei or the Palazzo Mattei alle Botteghe Oscure, is an urban palace located on via delle Botteghe Oscure #32 in the rione Sant'Angelo of Rome, Italy. A palace at the site was initially commissioned from the architect Nanni di Baccio Bigio between 1545 and 1564 by Alessandro Mattei; this structure was purchased in 1776, by the Caetani, and has undergone numerous refurbishments. The building contains a number of tenants, including the Brazilian embassy to the Vatican, but also houses the Fondazione Camillo Caetani, including its library. The interior decoration was begun by Alessandro Mattei, who employed the brothers Taddeo and Federico Zuccari in painting some of the works in the piano nobile. Cristoforo Roncalli painted the palace chapel, and collaborated with Paul Bril, to decorate some of the rooms. The Caetani family employed Antonio Cavallucci in some of the 18th-century decorations.

Sant'Angelo is the 11th rione of Rome, Italy, located in Municipio I. Often written as rione XI - Sant'Angelo, it has a coat of arms with an angel on a red background, holding a palm branch in its left hand. In another version, the angel holds a sword in its right hand and a scale in its left.Sant'Angelo, the smallest of Rome's rioni, lies along the Tiber river east of Tiber Island. Rioni bordering this district, clockwise from north to south, include Regola, Sant'Eustachio, Pigna, Campitelli, and Ripa. Sant'Angelo's western border is the river. The rione's terrain is low and flat and, until the construction of the Lungotevere, particularly susceptible to flooding from the river. The historical significance of Sant'Angelo is mainly the result of the presence here of the Roman Ghetto.

The Temple of the Nymphs was a temple in ancient Rome dedicated to the Nymphs, evidenced in several sources and generally identified with the remains on what is now via delle Botteghe Oscure. The temple was founded in the 3rd century BC or the early 2nd century BC. It was damaged by a fire in the mid 1st century BC and probably also affected by the citywide fire in 80 AD. This temple was on the Campus Martius. If still in use by the 4th-century, the temple would have been closed during the persecution of pagans in the late Roman Empire, when the Christian Emperors issued edicts prohibiting all non-Christian worship and sanctuaries.

"In Pescheria" refers to its location close to the fish market built in the ruins of the ancient Porticus Octaviae. The relics of St. Symphorosa and her seven sons were transferred to the Church of Sant'Angelo in Pescheria at Rome by Pope Stephen II in 752. A sarcophagus was found here in 1610, bearing the inscription: Hic requiescunt corpora SS. Martyrum Simforosae, viri sui Zotici (Getulii) et Filiorum ejus a Stephano Papa translata. This inscription refers to Saint Getulius and Saint Symphorosa, purported to be husband and wife, who had seven sons, who were also martyred. The remains of these saints were transferred to Sant'Angelo by Pope Stephen II in 752.The revolutionary "tribune" Cola di Rienzo was born near Sant'Angelo.

The Ghetto was abolished in 1870 after the reunification of Italy or Risorgimento, and the Ghetto wall was demolished in 1888. The rione Sant'Angelo, numbered as XI, is named after the church. The inscriptions found in S. Angelo, a valuable source illustrating the history of the Basilica, have been collected and published by Vincenzo Forcella.In the second chapel to the left inside the church are frescoes of the Madonna with Child and Angels attributed to Benozzo Gozzoli (c. 1450). During the late 14th century, Matteo de Baccari dedicated part of his inheritance to the Church of Sant'Angelo in Pescheria in Rome, specifically to the Chapel of St. Cosmo and Damian.
