A castle at Walterstown (111) in Moynalty parish is not depicted on the Down Survey (1656-8) barony or parish maps (http://downsurvey.tcd.ie/) but according to the Civil Survey (654-6) John Betah of Walterstown owned 220 acres there in 1640 together with ‘an old ruinate castle and a few cabins’ (Simington 1940, 300). John also owned land at Rathdrumnoe (Rathmanoo) and Rathstephen, and other members of the family owned almost all of Moynalty parish (ibid. 299-302). It is marked only on the 1908 ed. of the OS 6-inch map where it is described as the site of a castle. It is situated at the summit of a prominent hill. The foundations of a rectangular structure (int. dims 13.5m E-W; 8m N-S) survive in a deciduous wood.
The above description is derived from the published 'Archaeological Inventory of County Meath' (Dublin: Stationery Office, 1987). In certain instances the entries have been revised and updated in the light of recent research.
