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.

Palazzo Lante, also known as either Palazzo Medici Lante or Medici Lante della Rovere, is a Renaissance-style aristocratic palace located on Piazza Dei Caprettari #72, near the church of Sant'Eustachio in the rione named after the church in central Rome, Italy. Presently the palace houses both the offices of the national Institute of Nuclear Physics and the Institute of Culture Pantheon.

Sant'Ivo alla Sapienza (lit. 'Saint Ivo at the Sapienza (University of Rome)') is a Roman Catholic church in Rome. Built in 1642–1660 by the architect Francesco Borromini, the church is widely regarded a masterpiece of Roman Baroque architecture. The church is at the rear of a courtyard at 40, Corso del Rinascimento; the complex is now used by the State Archives of Rome.

Palazzo Giustiniani or the Piccolo Colle (Little Hill) is a palace on the Via della Dogana Vecchia and Piazza della Rotonda, in Sant'Eustachio, Rome. The palace contains the official residence of the President of the Senate of the Republic, the Sala Zuccari, the offices of the Life senators and former Presidents of Italy, and some administrative offices. From 1901 until 1985, it was also the seat of the Masonic order of the Grand Orient of Italy.

The Grand Orient of Italy (GOI) (Italian: Grande Oriente d'Italia) is an Italian masonic grand lodge founded in 1805; the viceroy Eugene of Beauharnais was instrumental in its establishment. It was based at the Palazzo Giustiniani, Rome, Italy from 1901 until 1985 and is now located at the Villa del Vascello. Its current Grand Master is Italian journalist Stefano Bisi.As of September 2015 the Grand Orient had 22,675 members in 842 lodges, a significant growth over the preceding three-year period.The international influence of the Grand Orient has decreased since it lost the official recognition of the "Home Grand Lodges" (of England, Ireland, and Scotland) owing to alleged corruption, although it remains regular in government and practice.

The Teatro Valle (literally Valley Theater) is a theatre and former opera house in Rome, Italy. It was built in 1726 for the Capranica family. In the middle of the 19th century, it switched from staging opera and theatre to only performances of spoken drama. After closing down in 2010, it was squatted in 2011, then evicted in 2014.

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.

Santa Chiara is a church in the rione Pigna, formerly the Campus Martius area of Rome dedicated to Saint Clare of Assisi. It is located at the corner of via Santa Chiara and via di Torre Argentina (where this street becomes via della Rotonda). It is about a block south of the Pantheon, at the piazza Santa Chiara. It was founded by Saint Charles Borromeo, who built a Franciscan convent (now used by the Pontifical French Seminary) and the church within the ruins of the Baths of Agrippa in 1592. It was restored in 1627, but at some later point the roof collapsed and it was abandoned. In 1883, the Congregation of the Holy Spirit acquired the property, and rebuilt the church, giving it a new facade designed by Luca Carimini in 1888. On the lower of the two levels, the main door is framed by two columns holding a semicircular tympanum with a decorated lunette. To the sides are niches with triangular tympanums, surmounted by circular windows. On the upper level there are seven windows surmounted by busts of saints. Below the windows is the Latin inscription: "DEO OPTIMO MAXIMO IN HONOREM IMMACVLATI CORDIS MARIAE ET CLARAE VIRGINIS". The triangular tympanum crowning the façade has a relief by Domenico Bartolini. Inside the church there is a single aisle. There are frescoes and paintings by the painter Virgilio Monti (1852-1942), the official painter to the Roman Church appointed by Pope Leo XIII. The church is still served by the Congregation of the Holy Spirit. The high altar has an altarpiece depicting the Holy Family, by Virgilio Monti.

The Contarelli Chapel or Cappella Contarelli is located within the church of San Luigi dei Francesi in Rome. It is famous for housing three paintings on the theme of Saint Matthew the Evangelist by the Baroque master Caravaggio. The paintings were Caravaggio's first major public commission and one that cemented his reputation as a master artist. The chapel commemorates the French cardinal Matthieu Cointerel.

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.
