The wall was initiated under the emperor Aurelian in the 3th century AD. Punctuated by a series of towers the section between the Porta Latina and Porta San Sebastiano is interesting.
From Wikipedia, the free encyclopedia (https://en.wikipedia.org/wiki/Aurelian_Walls)
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 They superseded the earlier Servian Wall: (https://en.wikipedia.org/wiki/Servian_Wall) built during the 4th century BC.
The Servian Wall was 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 (610 acres). In the 3rd century AD it was superseded by the construction of the larger Aurelian Walls as the city of Rome grew beyond the boundary of the Servian Wall.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 walls enclosed all the seven hills of Rome plus the Campus Martius and, on the right bank of the Tiber , the Trastevere district. The river banks within the city limits appear to have been left unfortified, although they were fortified along the Campus Martius. The size of the entire enclosed area is 1,400 hectares (3,500 acres).[1] The wall cut through populated areas: in reality the city at the time embraced 2,400 hectares or 6,000 acres. Pliny the Elder (https://en.wikipedia.org/wiki/Pliny_the_Elder) in the first century AD suggested that the densely populated areas, extrema tectorum (“the limits of the roofed areas”) extended 2.8 kilometres (1.7 mi) from the Golden Milestone in the Forum (Natural History 3.6
