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.
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.
Ponte Sant'Angelo, once the Aelian Bridge or Pons Aelius, meaning the Bridge of Hadrian, is a Roman bridge in Rome, Italy, completed in 134 AD by Roman Emperor Hadrian, to span the Tiber, from the city center to his newly constructed mausoleum, now the towering Castel Sant'Angelo. The bridge is faced with travertine marble and spans the Tiber with three arches; it was approached by means of ramp from the river. The bridge is now solely pedestrian, and provides a photogenic vista of the Castel Sant'Angelo. It links the rioni of Ponte (which was named after the bridge itself), and Borgo.
