The Wall of Aurelian encircles the Urbs Roma, protecting the city from any perceived threats — though, more often than not, it alone is enough to deter an attack. Made up of towering stone barriers fortified by battlements and punctuated by manned sentry towers, the wall casts a broad shadow over the bustling city below. The wall is crafted from enormous stone bricks and built to be utterly unyielding. At intervals, colossal gateways adorned with iron-studded doors grant controlled entry to the city as guardsmen question reasons for entry and search carts. To those on the inside, the wall is seen as a necessity that keeps them safe from the barbarian dangers of the outside world, but to those looking in, it often serves as nothing more than another divider.
