Eynsford Castle in Kent is a rare example of an early Norman enclosure castle built without a motte or keep. Constructed between 1085 and 1087 by William de Eynsford I, the castle's principal defence relied on an impressive curtain wall enclosing the site, parts of which survive to their full height. The site features a 12th-century great hall with external stairs, a substantial kitchen built between 1150 and 1175, remains of three garderobes built into the defensive walls, and a well that served as the castle's main water supply. This unusually designed fortress remained in continuous use until its abandonment after 1312, and today offers visitors insight into the distinctive defensive architecture of early Norman England.
