Hadleigh Castle is a late medieval enclosure castle situated on the Essex coast near Southend-on-Sea, founded by Edward III in 1365 as a coastal defence fortification against French invasion during the Hundred Years' War. The castle comprises a substantial curtain wall enclosing an irregular polygonal area, with corner towers and gatehouse structures typical of fourteenth-century military architecture. Associated with the main fortification are remains of a dam and mill complex, reflecting the economic and practical infrastructure of the medieval castle estate. The site remains prominently visible as earthwork and standing masonry, demonstrating the scale and strategic importance of royal coastal defences in later medieval England.
