The Pati Llimona Civic Centre is located at number 3, Regomir Street, in the Ciutat Vella district, in the historic centre of Barcelona.
In the interior courtyard of the Pati Llimona Civic Centre we can find another section of the Roman wall of the city of Barcelona. This wall was built during the 4th century AD. In this case, we can observe the magnificence of this wall, since the attached constructions are very different from the Roman parts.
The Roman wall of Barcelona had a height of about 10 meters, and a moat that was between 5 and 10 meters deep. The moat was where the city’s sewers flowed. In addition, between the moat and the wall there was a sentry walk.
