The Servian Wall is an ancient Roman defensive barrier constructed around the city of Rome in the early 4th century BC. The wall was built of volcanic tuff and was up to 10 m (33 ft) in height in places, 3.6 m (12 ft) wide at its base, 11 km (6.8 mi) long, and is believed to have had 16 main gates, of which only one or two have survived, and enclosed a total area of 246 hectares. In the 3rd century AD it was superseded by the construction of the larger Aurelian Walls as the city of Rome grew beyond the boundary of the Servian Wall.
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 They superseded the earlier Servian Wall built during the 4th century BC.
In 7 BC, Augustus divided the city of Rome into 14 administrative regions. These replaced the four regiones—or "quarters"—traditionally attributed to Servius Tullius, sixth king of Rome. They were further divided into official neighborhoods.
Castro Pretorio is the 18th rione of Rome (Italy), identified by the initials R. XVIII, and it is located within the Municipio I. The rione takes its name by the ruins of the Castrum Praetorium, the barracks of the Praetorian Guard, included in the Aurelian Walls.
Celio is the 19th rione of Rome, identified by the initials R. XIX, and is located within the Municipio I.
San Saba is the 21st rione of Rome, identified by the initials R. XXI. It is located within the Municipio I, and takes its name from the Basilica of San Saba, which is located there.
The Aqua Appia was the first Roman aqueduct, constructed in 312 BC by the co-censors Gaius Plautius Venox and Appius Claudius Caecus, the same Roman censor who also built the important Via Appia.
The Porta San Sebastiano is the largest and one of the best-preserved gates passing through the Aurelian Walls in Rome (Italy).
The Tomb of the Scipios, also called the hypogaeum Scipionum, was the common tomb of the patrician Scipio family during the Roman Republic for interments between the early 3rd century BC and the early 1st century AD. Then it was abandoned and within a few hundred years its location was lost.
Via Asinaria was an ancient Roman road that started from Porta Asinaria in the Aurelian walls (Rome). It was somehow connected with the Via Latina, as it is reported that Belisarius, during its advance on Rome, left the Via Latina to enter the city from Porta Asinaria; the latter was considered one of the main accesses for those coming from the south, as in ancient times the 17th-century Porta San Giovanni didn't exist.
In ancient Rome, the Piscina Publica was a public reservoir and swimming pool located in Regio XII. The region itself came to be called informally Piscina Publica from the landmark. The piscina was situated in the low-lying area between the Via Appia, the Servian Wall, and the northeast slope of the Aventine Hill, an area later occupied by the Baths of Caracalla.
The Castra Albana was an ancient Roman legionary fortress of the Legio II Parthica founded by the Emperor Septimius Severus (193-211) on the site of the present Albano Laziale.
The Appian Way Regional Park is the second-largest urban park of Europe, after Losiny Ostrov National Park in Moscow. It is a protected area of around 4580 hectares, established by the Italian region of Latium. It falls primarily within the territory of Rome but parts also extend into the neighbouring towns of Ciampino and Marino.
Viale Aventino is a street that links Piazza di Porta Capena and Piazza Albania in Rome (Italy). It marks the boundary between the Rione Ripa and San Saba.
The Regio I Porta Capena is the first regio of imperial Rome, under Augustus's administrative reform. Regio I took its name from the Porta Capena, a gate of the Servian Walls, through which the Appian Way entered the city prior to the construction of the Aurelian Walls.
The Porta Viminale was a gateway in the Servian Wall of ancient Rome, at the centre of the most exposed stretch of the wall between the Porta Collina and the Porta Esquilina. These three gates and the Porta Querquetulana were the oldest in the wall.
The Museo delle Mura is an archaeological museum in Rome, Italy. It is housed in the first and second floors of the Porta San Sebastiano at the beginning of the Appian Way. It provides an exhibition on the walls of Rome and their building techniques, as well as the opportunity to walk along the inside of one of the best-preserved stretches of the Aurelian Wall. The museum is free of charge.
The Almone is a small river of the Ager Romanus, a few miles south of the city of Rome. Today the river is polluted and is channelled to a sewage treatment plant and no longer reaches its natural confluence with the Tiber.
Porta Caelimontana and Porta Querquetulana were two city gates that opened in the Servian Wall in Rome (Italy); only the first one is still existing.
