Described by Stanley in the nieneteenth century as 'Midway between Killeigh and the river are patches of the 'double ditch' a fosse carried across terra firma, from a great bog which enters the Iregan dominions on one side. The work is not half a mile in length' (Stanley 1871-3, 81). The above description is derived from the published 'Archaeological Inventory of County Offaly' (Dublin: Stationery Office, 1997). In certain instances the entries have been revised and updated in the light of recent research. Date of upload: 23 May 2011
