London Wall

The London Wall is a defensive wall first built by the Romans around the strategically important port town of Londinium in c. AD 200, as well as the name of a modern street in the City of London, England.

Roman London was, from around 120–150, protected by a large fort, with a large garrison, that stood to its north-western side. The fort, now referred to as the Cripplegate Fort, was later incorporated into a comprehensive city-wide defence, with its strengthened northern and western sides becoming part of the Wall which was built around 200. The incorporation of the fort's walls gave the walled area its distinctive shape in the north-west part of the city.
