London Wall
The London Wall was the defensive wall built by the Romans around Londinium. Londinium was then, as now, the most important port town on the River Thames.
London Wall is now the name of a road in the City of London. It runs along part of the course of the old wall. Until the later Middle Ages, the wall defined the boundaries of the City of London.
