What is recorded here

Greenville or Garryduff holds a vanished ringfort, visible only through a circular grove of trees drawn on an 1840 map. Reynolds identified a small fort built on rock, but quarrying chewed through its interior from the northeast to the south. The stones are gone, yet the trees still mark the shape of what people lived inside before the rock was taken.

Not visible at ground level. Depicted as a circular grove of trees on 1840 edition of the OS 6-inch map. Described by Reynolds (1977) as a small ringfort built on a rock outcrop which has been partly quarried away causing damage to the ringfort's interior from NE through E to S. 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
