Borgo (sometimes called also I Borghi), is the 14th historic district (rione) of Rome, Italy. It lies on the west bank of the Tiber, and has a trapezoidal shape. Its coat of arms shows a lion (after the name "Leonine City", which was also given to the district), lying in front of three mounts and a star. These - together with a lion rampant - are also part of the coat of arms of Pope Sixtus V who annexed Borgo as fourteenth rione to the city of Rome.
The Borgo borders the Vatican City (Saint Peter's Square) to the west, the Tiber to the east, Prati to the north, the quartiere Aurelio to the southwest and Trastevere to the south.
The territory of the quarter includes a level part, which is made of the alluvial sands of Tiber, and a hilly zone, which coincides with the clay-laden slopes of the Vatican hill.
In administrative terms, the Borgo, unlike Trastevere, does not belong to the Center (I Municipio), but to the XVII Municipio, together with the rione of Prati and the quartieri Trionfale and Della Vittoria (around Piazza Mazzini).
The main roads run east-west and (with the noteworthy exception of the modern Via della Conciliazione) are not named Vie, but Borghi.
Although heavily transformed during the first half of the 20th century, the Borgo maintains its historical importance as a forecourt to Saint Peter's Basilica and the Vatican Palace.
