Overview

History & context

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.

The end of Roman rule in Britain, around 410, led to the wall falling into disrepair. It was restored in the late Anglo-Saxon period, a process generally thought to have begun under Alfred the Great after 886. Repairs and enhancements continued throughout the medieval period. The wall largely defined the boundaries of the City of London until the later Middle Ages, when population rises and the development of towns around the city blurred the perimeter.

From the 18th century onward, the expansion of the City of London saw large parts of the wall demolished, including its city gates, to improve traffic flow. Since the Second World War, conservation efforts have helped to preserve surviving sections of the city wall as scheduled monuments.

The long presence of the walls has had a profound and continuing effect on the character of the City of London, and surrounding areas. The walls constrained the growth of the city, and the location of the limited number of gates and the route of the roads through them shaped development within the walls, and more fundamentally, beyond them. With few exceptions, the modern roads heading into the former walled area are the same as those which passed through the former medieval gates.

It has origins as an initial mound wall and ditch from c. AD 100 and a fort, now called Cripplegate fort after the city gate (Cripplegate) that was subsequently built on its northern wall later on, in 120–150

The fort was later incorporated into a city-wide defence in the late 2nd or early 3rd century AD, though the reason for such a large and expensive fortification is unknown. The fort's north and west walls were thickened and doubled in height to form part of the new city wall. The incorporation of the fort's walls gave the walled area its distinctive shape in the north-west part of the city.

It continued to be developed until at least the end of the 4th century, making it among the last major building projects undertaken by the Romans before the Roman departure from Britain in 410. Reasons for its construction may have been connected to the invasion of northern Britain by Picts who overran Hadrian's Wall in the 180s. This may be linked to the political crisis that emerged in the late 2nd century when the governor of Britain Clodius Albinus was consolidating his power after claiming the right of succession as Roman emperor. After a struggle with his rival Septimius Severus, Albinus was defeated in 197 at the Battle of Lugdunum (near Lyon, France). The economic stimulus provided by the wall and Septimius's subsequent campaigns in Scotland improved Londinium's financial prosperity in the early 3rd century.
