Outlined — Glaskill (ballycowan By.)

Unlocated tree-ring described in 1942 (ITA Survey 1942) as, 'a very slight mound at SW end of ridge, steep slope S & W, probably good view, but now situated in very thick wood. Apparently in a prominent position. Two low banks of loosely piled stones 9' [2.7m] apart now bound and enclose the circular area, which cannot be measured but is c. 30yds [27m] across. This place might be a small fort, but may well be a folly, though there are no traces e.g. of a summerhouse on it' (ITA Survey 1942, SMR File). Depicted as a circular landscape feature located in the centre of Glaskill Wood which is accessed via a network of pathways indicated on all editions of the OS 6-inch maps. Probably built as an ornamental feature in the 19th century as part of the landscaping of Glaskill Wood. Not indicated as an antiquity on any edition of the OS 6-inch maps. The cartographic evidence would suggest that this is not an archaeological monument but rather a tree-ring of 19th century date. 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/revision: 28 December 2011
