Castle

Situated on high ground at the edge of an old river valley overlooking the Castletown River to the SW and consisting of an earth and stone mound (max. diam. at base c. 30m, summit partly destroyed, H c. 5m) with traces of a wide filled-in fosse (Wth 8.1m, D c. 1m) at the E. Part of the W side of the mound appears to have collapsed into the old river valley which may have been the original course of the Castletown River. Site quarried out and destroyed c. 1979. (Morris 1906, 40) The above description is derived from both the published 'Archaeological Inventory of County Louth' (Dublin: Stationery Office, 1986) and the 'Archaeological Survey of County Louth' (Dublin: Stationery Office, 1991). In certain instances the entries have been revised and updated in the light of recent research. Date of upload: 17 July 2007

Built in the 12th or 13th century, likely by a local Anglo-Norman lord or military commander, Castlecarragh motte served as a strategic defensive and administrative outpost in a frontier region. Its location overlooking a river valley highlights its importance in controlling local trade routes and asserting authority during the medieval colonization of Ireland.
