Canterbury City Wall

Canterbury City Wall represents one of Britain's most magnificent medieval fortifications, with over half of its original circuit surviving to enclose an area of 130 acres. First constructed by Romans between 270–280 AD as stone walls with earth banks, the structure was later retained by Anglo-Saxons and rebuilt during the medieval period. Eight medieval gates—including the West Gate Tower, erected in 1380—pierce the walls, which originally extended nearly 2 miles around the city. The West Gate now houses a museum exploring Canterbury's fortification history, making this a significant testament to layered architectural and military innovation spanning multiple centuries.
