London Wall

 

From its earliest foundation the Roman city of Londinium was almost certainly surrounded by some kind of fortification. As well as providing defence, the construction of a stone wall represented the status of the city. Using the evidence of excavated coins, archaeologists have dated the construction of the first stone city wall to between ad 190 and 225.

The wall was about 2.5 miles (4 kilometres) long, enclosing an area of about 330 acres (134 hectares); it originally included four city gates with an additional entrance into the legionary fortress at Cripplegate. In front of the eastern face of the wall was a ditch, which was up to 6 feet (1.8 metres) deep and 16 feet (4.8 metres) across.

How to Find It: This section of the wall is located at the edge of a small garden to the southeast of Tower Hill underground station. From the station the garden is accessed just off the path to the Tower of London, and is halfway down the steps to the Tower Hill underpass on the left hand side..
