PANORAMIC VIEW The church of the Santissima Trinità dei Monti, often called merely the Trinità dei Monti (French: La Trinité-des-Monts), is a Roman Catholic late Renaissance titular church in Rome, central Italy. It is best known for its position above the Spanish Steps which lead down to the famous Piazza di Spagna. The church and its surrounding area (including the Villa Medici) are a French State property.

The Spanish Steps (Italian: Scalinata di Trinità dei Monti) in Rome, Italy, climb a steep slope between the Piazza di Spagna at the base and Piazza Trinità dei Monti, dominated by the Trinità dei Monti church, at the top. The monumental stairway of 135 steps was built with French diplomat Étienne Gueffier's bequeathed funds of 20,000 scudi, in 1723–1725,[citation needed] linking the Trinità dei Monti church under the patronage of the Bourbon kings of France and the Spanish Embassy at the top of the steps to the Holy See in the Palazzo Monaldeschi at the bottom of the steps. The stairway was designed by architects Francesco de Sanctis and Alessandro Specchi.

The Trevi Fountain (Italian: Fontana di Trevi) is an 18th-century fountain in the Trevi district in Rome, Italy, designed by Italian architect Nicola Salvi and completed by Giuseppe Pannini and several others. Standing 26.3 metres (86 ft) high and 49.15 metres (161.3 ft) wide,[1] it is the largest Baroque fountain in the city and one of the most famous fountains in the world. The fountain has appeared in several films, including Roman Holiday (1953); Three Coins in the Fountain (1954); Federico Fellini's classic, La Dolce Vita (1960); Sabrina Goes to Rome (1998); and The Lizzie McGuire Movie (2003).[2]

Although the Pantheon has stood from antiquity, the area in front of it had over the centuries become choked with a maze of sheds and small shops that had grown up around its columns. These medieval accretions were cleared by order of Pope Eugenius IV (1431–39) and the piazza was laid out and paved.[1] It took its name from the Pantheon, which had been converted in the 7th century AD into a Christian church dedicated to "St. Mary and the Martyrs" but informally known as Santa Maria Rotonda.[2] The piazza is roughly rectangular, approximately 60 meters north to south and 40 meters east to west, with a fountain and obelisk in the center and the Pantheon on the south side.

The Pantheon "[temple] of all the gods") is a former Roman temple and, since 609 AD, a Catholic church 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 of the oculus and the diameter of the interior circle are the same, 43 meters

The Temple of Hadrian is an ancient Roman structure dedicated to the deified emperor Hadrian by his adoptive son and successor Antoninus Pius in 145 This temple was previously known as the Basilica of Neptune but has since been properly attributed as the Temple of Hadrian completed under Antoninus Pius. With one cella wall and eleven columns from the external colonnade surviving, the remains of the temple have been incorporated into a later building in the Piazza di Pietra, whereby its facade, alongside the architrave which was reconstructed, later on, was incorporated into a 17th-century papal palace by Carlo Fontana, now occupied by Rome's Chamber of commerce. While only part of the structure remains, excavations and scholarship have provided us with information regarding its construction techniques and stylistic influences, helping us recreate the building dynamics and significance of the Temple of Hadrian in Imperial Rome.

It was built atop the ruins of the ancient baths of Nero, next to Piazza Navona. The terrain had been acquired in the Middle Ages by the monks of the Abbey of Farfa, who later ceded it to France. The new building was begun at the end of the 15th century and completed in 1505, for the Medici family. It housed two Medici cardinals and cousins, Giovanni and Giulio, who both later became popes as Leo X and Clement VII, respectively. Catherine de' Medici, Clement VII's niece, also lived here before she was married to Henry, son of King Francis I of France in 1533. Cardinal Francesco Maria Del Monte, patron of the artist Caravaggio, lived there until his death in 1627. The palace takes its name from Madama Margherita of Austria, the illegitimate daughter of Emperor Charles V, who married another illegitimate son, Alessandro de' Medici, and, after his death, Ottavio Farnese. Thus part of the art collection of the Florentine Medici family was inherited by the Farnese family.

Piazza Navona is one of the most famous squares in Rome, built by the Pamphili family. Its shape is that of an ancient stadium: it was built in a monumental style at the behest of Pope Innocent X.
