The Aurelian Walls are a series of defensive walls that were built in the 3rd century AD to protect the city of Rome. They were named after the Emperor Aurelian, who ordered their construction.
The Aurelian Walls were built during a time when Rome was under threat from invading barbarian tribes. The city's existing defenses had fallen into disrepair, and Aurelian realized that new walls were needed to protect the city from attack.
