The Tiber is the third-longest river in Italy and the longest in Central Italy, rising in the Apennine Mountains in Emilia-Romagna and flowing 406 km (252 mi) through Tuscany, Umbria, and Lazio, where it is joined by the River Aniene, to the Tyrrhenian Sea, between Ostia and Fiumicino. It drains a basin estimated at 17,375 km2 (6,709 sq mi). The river has achieved lasting fame as the main watercourse of the city of Rome, which was founded on its eastern banks.
Marcus Aurelius Probus was Roman emperor from 276 to 282. Probus was an active and successful general as well as a conscientious administrator, and in his reign of six years he secured prosperity for the inner provinces while withstanding repeated invasions of barbarian tribes on almost every sector of the frontier.
The Via Flaminia or Flaminian Way was an ancient Roman road leading from Rome over the Apennine Mountains to Ariminum (Rimini) on the coast of the Adriatic Sea, and due to the ruggedness of the mountains was the major option the Romans had for travel between Etruria, Latium, Campania, and the Po Valley. The section running through northern Rome is where Constantine the Great, allegedly, had his famous vision of the Chi Rho, leading to his conversion to Christianity and the Christianization of the Roman Empire.
The ancient Romans were the first civilization to build large, permanent bridges. Early Roman bridges used techniques introduced by Etruscan immigrants, but the Romans improved those skills, developing and enhancing methods such as arches and keystones. There were three major types of Roman bridge: wooden, pontoon, and stone. Early Roman bridges were wooden, but by the 2nd century stone was being used. Stone bridges used the arch as their basic structure, and most used concrete, the first use of this material in bridge-building.
Trastevere is the 13th rione of Rome: it is identified by the initials R. XIII and it is located within Municipio I. Its name comes from Latin trans Tiberim, literally 'beyond the Tiber'.
The Via Aurelia is a Roman road in Italy constructed in approximately 241 BC. The project was undertaken by Gaius Aurelius Cotta, who at that time was censor. Cotta had a history of building roads for Rome, as he had overseen the construction of a military road in Sicily connecting Agrigentum and Panormus.
The Leonine City is the part of the city of Rome which, during the Middle Ages, was enclosed with the Leonine Wall, built by order of Pope Leo IV in the 9th century.
The Pons Sublicius is the earliest known bridge of ancient Rome, spanning the Tiber River near the Forum Boarium downstream from the Tiber Island, near the foot of the Aventine Hill. According to tradition, its construction was ordered by Ancus Marcius around 642 BC, but this date is approximate because there is no ancient record of its construction. Marcius wished to connect the newly fortified Janiculum Hill on the Etruscan side to the rest of Rome, augmenting the ferry that was there. The bridge was part of public works projects that included building a port at Ostia, at the time the location of worked salt deposits.
The Aurelian Walls are a line of city walls built between 271 AD and 275 AD in Rome, Italy, during the reign of the Roman Emperor Aurelian. They superseded the earlier Servian Wall built during the 4th century BC.
Ponte is the 5th rione of Rome, identified by the initials R. V, and is located in Municipio I. Its name comes from Ponte Sant'Angelo, which connects Ponte with the rione of Borgo. This bridge was built by Emperor Hadrian in 134 AD to connect his mausoleum to the rest of the city. Though Pope Sixtus V changed the rione limits, so that the bridge belongs now to Borgo, not to Ponte anymore, the area has kept its name and a bridge as its coat of arms.
The Pons Fabricius or Ponte dei Quattro Capi, is the oldest Roman bridge in Rome, Italy, still existing in its original state. Built in 62 BC, it spans half of the Tiber River, from the Campus Martius on the east side to Tiber Island in the middle. Quattro Capi refers to the two marble pillars of the two-faced Janus herms on the parapet, which were moved here from the nearby Church of St Gregory in the 14th century.
The Pons Cestius is an ancient Roman bridge connecting the right bank of the Tiber with the west bank of Tiber Island in Rome, Italy. In Late Antiquity, the bridge was replaced and renamed the Pons Gratiani. It is also known as Ponte San Bartolomeo. No more than one third of the present stone bridge is of ancient material, as it was entirely rebuilt and extended in the 19th century after numerous earlier restorations.
The Pons Aemilius is the oldest Roman stone bridge in Rome. Preceded by a wooden version, it was rebuilt in stone in the 2nd century BC. It once spanned the Tiber, connecting the Forum Boarium, the Roman cattle market, on the east with Trastevere on the west. A single arch in mid-river is all that remains today, lending the bridge its name Ponte Rotto.
Porta San Pancrazio is one of the southern gates of the Aurelian walls in Rome, Italy.
Porta Settimiana is one of the gates of the Aurelian walls in Rome, Italy. It rises at the northern vertex of the rough triangle traced by the town walls, built by Emperor Aurelian in the 3rd century, in the area of Trastevere an up through the Janiculum.

The Pons Neronianus or Bridge of Nero was an ancient bridge in Rome built during the reign of the emperors Caligula or Nero to connect the western part of the Campus Martius with the Ager Vaticanus, where the Imperial Family owned land along the Via Cornelia.
The Pons Agrippae was an ancient bridge across the River Tiber in Rome. It was located 160 metres above the Ponte Sisto, and is known from an inscribed cippus set up by the curatores riparum during the Principate of the Emperor Claudius, suggesting it was built during or before the reign of Claudius. It was restored in 147 AD. The bridge is named after Marcus Vipsanius Agrippa, a close friend of the Emperor Augustus. Agrippa married Julia, the daughter of Augustus, and the couple lived in a villa on the opposite bank of the River Tiber. To connect his villa to the Field of Mars, where Agrippa had built several important monuments, it has been suggested that Agrippa constructed the Pons Agrippae.
Lungotevere is an alley or boulevard running along the river Tiber within the city of Rome. The building of the Lungoteveres required the demolition of the former edifices along the river banks and the construction of retaining walls called muraglioni.
The Regio XIV Transtiberim is the fourteenth regio of imperial Rome, under Augustus's administrative reform. Meaning "across the Tiber", the Regio took its name from its position on the west bank of the Tiber River.
