These early walls lasted beyond the fall of the Empire, and the defences encouraged several early Christian foundations to establish themselves in Worcester during the troubled 6th and 7th centuries. The Anglo-Saxons expanded Worcester in the 890s, forming a new walled, planned city, called a burh. The burh utilised the southern stretches of the old Roman walls, but pushed further north to enclose a much larger area. The Anglo-Saxon city walls were maintained by a share of taxes on a local market and streets, in an agreement reinforced by a royal charter.

After the Norman conquest of England in the 11th century a motte and bailey castle was constructed on the south side of the city, but the Norman rulers continued to use the older burh walls, despite the city having expanded beyond these defences in the north and south-east. During the years of the Anarchy in the 1140s, Worcester was successfully attacked several times; after the war a new city wall was built to improve the city’s defences. The new walls, completed by the early 13th century, were constructed of stone and had three main gates. They were maintained in good condition into the 17th century.

During the English Civil War in the 1640s the old medieval walls were reinforced with modern earthwork bastions and an outlying fort, called a sconce. Worcester changed hands several times during the conflict, and after the war ended the newer fortifications were dismantled. During the 18th century the older medieval stone walls and gatehouses were sold and mostly destroyed: by the 20th century, few parts survived. Post-war archaeology in the 1950s and 1960s and construction work in the 1970s revealed previously hidden stretches of the wall, and in the 21st century plans have been drawn up to improve the conservation and maintenance of this historic monument.
