Hadleigh Castle is a medieval enclosure castle situated on the Essex coast near Southend-on-Sea. Built in the 1360s by Edward III as a coastal defence against French raids during the Hundred Years War, the castle comprises a substantial stone-built curtain wall with towers commanding views across the Thames Estuary. The site originally incorporated associated structures including a dam and mill, reflecting the practical infrastructure required to sustain the garrison and support local economic activity. The castle's remains, comprising portions of the defensive wall and corner towers, survive as significant testimony to fourteenth-century military architecture and royal investment in coastal fortification.
