Piazza del Popolo ist ein großer städtischer Platz in Rom. Der Name bedeutet im modernen Italienisch wörtlich „Volksplatz“, aber historisch leitet er sich von den Pappeln ab (populus auf Latein, pioppo auf Italienisch), nach denen die Kirche Santa Maria del Popolo in der nordöstlichen Ecke der Piazza benannt ist.

Piazza di Spagna („Spanischer Platz“) am Fuße der Spanischen Treppe ist einer der berühmtesten Plätze in Rom, Italien. Er verdankt seinen Namen dem Palazzo di Spagna, dem Sitz der spanischen Botschaft beim Heiligen Stuhl. Dort befindet sich auch die berühmte Säule der Unbefleckten Empfängnis der Heiligen Jungfrau Maria.

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 in 1723–1725. 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, 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).

The Pantheon 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 on the site of an earlier temple commissioned by Marcus Agrippa during the reign of Augustus.

Piazza Navona is a public open space in Rome. It is built on the site of the Stadium of Domitian, built in the 1st century AD, and follows the form of the open space of the stadium. The ancient Romans went there to watch the agones ("games"), and hence it was known as "Circus Agonalis" ("competition arena"). It is believed that over time the name changed to in avone to navone and eventually to navona.
