The Circus Maximus is an ancient Roman circus, dedicated to horse racing, built in Rome. Located in the valley between the Palatine and the Aventine, it has been remembered as a venue for games since the beginning of the city's history: in the valley there would have been the mythical episode of the rape of the Sabine women, on the occasion of the games called by Romulus in honor of the god Consus. Certainly the large flat space and its proximity to the Tiber landing, where trade had taken place from the most remote antiquity, meant that the site constituted, from the foundation of the city, the elective space in which to conduct market activities and exchanges with other populations, and - consequently - also the related ritual activities (think of the Hercules maxim) and socialization, such as games and competitions.

The Jewish ghetto of Rome is among the oldest ghettos in the world; in fact it arose 40 years after the one in Venice which is the first ever. The term derives from the name of the Venetian district, gheto, where there was a foundry (precisely gheto in Venetian), where the Jews of that city were forced to reside; another possible etymology traces the origin of this word to the Hebrew גט ghet (pl. גיטים ghittim or גיטין ghittin), which means separation.

Until the fifteenth century the square did not exist as such, and in its place there was a flowery meadow with some cultivated gardens, hence the name. According to an unreliable tradition, the square should instead be named after Flora (a woman loved by Pompey, who had built his theater nearby). [1] The square gave its name to the long road axis known in the fifteenth century as Via Florea which connected Sant'Angelo in Pescheria with the S. Angelo bridge, passing through the current Via Portico di Ottavia, via dei Giubbonari (formerly Via Pelamantelli), Via del Pellegrino and via dei Banchi Vecchi [2]. The same route from Via dei Giubbonari to Via del Pellegrino also took the name of Via Mercatoria from the 15th century.

The Trevi Fountain is the largest and one of the most famous fountains in Rome. It was built on the facade of Palazzo Poli (more properly called Palazzo Conti di Poli), by Nicola Salvi. The competition held by Pope Clement XII in 1731 had been won by the French sculptor Lambert-Sigisbert Adam, but later the task passed to Salvi (it is said that the pope did not want to entrust the work to a foreigner, but another version explains that Adam was to return to France) which began in 1732. It was completed in 1762 by Giuseppe Pannini and stylistically belongs to the late Baroque. The fountain was built with travertine, marble, plaster, stucco and metals.
