The Aurelian Walls (Le Mura Aureliane) in Rome were built in the third century A.D. and are about 19 kilometers long. Works begun by Emperor Aurelian during a time of insecurity throughout Italy and the empire. Fortification walls were restored several times in antiquity, but are still well-preserved. Moreover, they had 17 major gates and several smaller openings.

Emperor Aurelian

Emperor Aurelian (270-275 A.D.), after five centuries of unopposed domination, decided that the city needs a defensive wall to protect it against invaders as the barbarian tribes near the north borders of the Roman Empire.

From the first century B.C. until the third century A.D., Rome’s military forces were powerful and the city didn’t need a protective wall

However, there was a small number of soldiers tasked with patrolling the fortifications and the Aurelian Walls helped to protect the city until the 19th-century.

Building of the Wall

Originally, the Aurelian Walls were 19 kilometers long (12 miles) and 6-8 meters high (20 feet). The wall included a square tower about 30 meters (100 feet). Moreover, it was completed by Probus, the successor of Emperor Aurelian.

Several large monuments and buildings are incorporated in the structure. These buildings include Castel Sant’Angelo, Amphitheater Castrense, the Pyramid of Cestius, and a section of the Aqua Claudia aqueduct.

A restoration of the wall by Arcadius and Honorius in 403 is attested by the inscriptions on the Portae Portuensis, Praenestina, and Tiburtina. Moreover, repairs by Theodoric and by Cassiodorus are attested by brick stamps.
