HURSTMONCEAUX (also HERSTMONCEUX), a village in Sussex, England, 9 m. N.E. of Eastbourne. Pop. (1921) The village takes its name from Waleran de Monceux. lord of the manor after the Conquest, but the century castle, for the ruins of which the village is famous, was built in the reign of Henry VI. by Sir Roger de Fiennes. Towers flank the corners, and there is a beautiful turreted entrance gate, but only the foundations of most of the buildings ranged round the inner courts are to be traced. The church of All Saints is Early English. Much material from the castle was used in the erection of Hurstmon ceaux Place, a mansion of the 18th century.
