Castle

National Monument in state ownership No. 134. Situated on a marked S-facing slope with a very steep slope dropping to the marshy floor of the Slaney River (100m S), and overlooking the fording point at Ballyhubbock Bridge. Circular steep-sided platform (diam. 41m; H 4.5-5.5m) encircled by a fosse (Wth 3-4m; D 0.2-0.7m). There are two causeways, one of which at the NW (Wth 1m) crosses the fosse at an angle and runs into a narrow ramp which leads up to the motte summit. This may be an original feature. A largely natural, level, roughly rectangular, platform (dims. 25m E-W; 16m N-S) 28m S of the motte on the lip of the 15m drop to the river floor may be an associated feature. The motte is probably associated with the Anglo-Norman borough of Donaghmore c. 500m to the NE (WI021-069002-). The above description is derived from the published 'Archaeological Inventory of County Wicklow' (Dublin: Stationery Office, 1997). In certain instances the entries have been revised and updated in the light of recent research. Date of upload/revision: 17 December 2008 This monument is subject to a preservation order made under the National Monuments Acts 1930 to 2014 (PO no. 109/1940).

Built in the 12th or 13th century, likely by Anglo-Norman settlers, the motte at Castleruddery Lower was strategically positioned to control the Slaney River crossing at Ballyhubbock Bridge, reflecting the importance of riverine access in medieval military and trade networks.
