Piazza della Rotonda

The Fontana del Pantheon (English: Fountain of the Pantheon) was commissioned by Pope Gregory XIII and is located in the Piazza della Rotonda, Rome, in front of the Roman Pantheon. It was designed by Giacomo Della Porta in 1575 and sculpted out of marble by Leonardo Sormani.In 1711, Pope Clement XI requested that the fountain be modified and had Filippo Barigioni design a new layout, which included a different basin, made of stone, and the Macuteo obelisk, created during the period of Ramses II, set in the centre on a plinth with four dolphins decorating the base. In 1886, the original marble figures were removed, and replaced with copies by Luigi Amici. Today, the originals can be seen in the Museum of Rome. Fontana del Pantheon was the model to Francesco Robba for the Robba fountain, which stands at Town Square in Ljubljana, the capital of Slovenia. It is one of the city's most recognisable symbols.In April 2018 James Pallotta offered to donate €230,000 towards the restoration the fountain and also the fontana dei Leoni in Piazza del Popolo.

The Pantheon (UK: , US: ; Latin: Pantheum, from Greek Πάνθειον Pantheion, "[temple] of all the gods") is a former Roman temple and since 609 AD, a Catholic church (Basilica di Santa Maria ad Martyres or Basilica of St. Mary and the Martyrs), in Rome, Italy, on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus (27 BC – 14 AD). It was rebuilt by the emperor Hadrian and probably dedicated c. 126 AD. Its date of construction is uncertain, because Hadrian chose not to inscribe the new temple but rather to retain the inscription of Agrippa's older temple, which had burned down.The building is cylindrical with a portico of large granite Corinthian columns (eight in the first rank and two groups of four behind) under a pediment. A rectangular vestibule links the porch to the rotunda, which is under a coffered concrete dome, with a central opening (oculus) to the sky. Almost two thousand years after it was built, the Pantheon's dome is still the world's largest unreinforced concrete dome. The height to the oculus and the diameter of the interior circle are the same, 43 metres (142 ft).It is one of the best-preserved of all Ancient Roman buildings, in large part because it has been in continuous use throughout its history: since the 7th century, it has been a church dedicated to St. Mary and the Martyrs (Latin: Sancta Maria ad Martyres) but informally known as "Santa Maria Rotonda". The square in front of the Pantheon is called Piazza della Rotonda. The Pantheon is a state property, managed by Italy's Ministry of Cultural Heritage and Activities and Tourism through the Polo Museale del Lazio. In 2013, it was visited by over 6 million people. The Pantheon's large circular domed cella, with a conventional temple portico front, was unique in Roman architecture. Nevertheless, it became a standard exemplar when classical styles were revived, and has been copied many times by later architects.

The Arch of Pietas (Latin : Arcus Pietatis) was an ancient Roman triumphal arch to the north of the Pantheon on the Campus Martius in Rome.

The Amphitheater of Caligula (Latin : Amphitheatrum Caligulae) was an Roman amphitheater, built during the reign of the emperor Caligula and demolished only a few years after its construction. It was sited on the Campus Martius in Rome, probably near the Saepta Julia, since the inscription mentioning it was just to the north of the Saepta.Work was begun on the amphitheater between 37 and 41 by Caligula, who wished to give Rome a second stone amphitheater alongside that of Statilius Taurus. Still incomplete on his death, it was abandoned and demolished by Claudius. Around 46, Claudius repaired the Aqua Virgo, damaged by the construction of the amphitheater. His restoration was marked by an inscription on the Arch of Claudius, which formed part of the aqueduct and spanned the Via Lata; this includes the phrase "[…] AQUAE VIRGINIS DISTVRBATOS PER C(AIVM) CAESAREM" (of the Aqua Virgo, damaged by C[aius] Caesar).

The Basilica of Neptune (Latin: basilica Neptuni) was a basilica built in Rome by Marcus Vipsanius Agrippa in honour of Neptune and in celebration of his naval victories at Mylae, Naulochus and Actium.

The Baths of Nero (Thermae Neronis) or Baths of Alexander (Thermae Alexandrinae) were a complex of ancient Roman baths on the Campus Martius in Rome, built by Nero in either 62 or 64 and rebuilt by Alexander Severus in 227 or 229. It stood between the Pantheon and the Stadium of Domitian and were listed among the most notable buildings in the city by Roman authors and became a much-frequented venue. These thermae were the second large public baths built in Rome, after the Baths of Agrippa, and it was probably the first "imperial-type" complex of baths, with a monumental scale and symmetrical, axially-planned design. While in the sixteenth century the foundations of the caldarium were still visible, nothing else of the structure remains above ground except some fragments of walls incorporated into the structure of Palazzo Madama.

The Teatro Capranica is a theatre situated at 101 Piazza Capranica in the Colonna district of Rome. Originally constructed in 1679 by the Capranica family and housed in the early Renaissance Palazzo Capranica, it was the second public theatre to open in Rome. It was the site of many premieres of Baroque operas including Caldara's Tito e Berenice, Scarlatti's Griselda, and Vivaldi's Ercole su'l Termodonte. The Capranica ceased operating as a full-scale theatre and opera house in 1881 and in 1922 was converted into a cinema. Following the closure of the cinema in 2000, it has functioned on a hire basis as a conference and performance venue.
