What is recorded here

Situated on a valley floor to the W of a stream. A tower is indicated at Rantauan on Petty's Down Survey (1656-8) barony map, for which see this web-page accessed on 13/04/2016 http://downsurvey.tcd.ie/down-survey-maps.php#bm=Castlerahan&c=Cavan Davies recorded 'walls of mortar and rubble' enclosing a rectangular area which he thought unlikely to be ancient (1947a, 99). However, there are now no visible remains of this structure at ground level. The above description is derived from the published 'Archaeological Inventory of County Cavan' (Dublin: Stationery Office, 1995). In certain instances the entries have been revised and updated in the light of recent research. Date of revision: 13 April, 2016
