A significant reassessment by Helen Roche of the construction date for the Great Circle: ‘The dating of the Embanked Stone Circle at Grange, Co. Limerick’ in Roche, Grogan, Bradley, Coles and Raftery (eds.): ‘From Megaliths to Metal – Essays in honour of George Eogan’, 2004, 109-116.
The most recent pottery-type, found at a position which would have predated the monument – in this case beneath the bank on the old ground surface – was ‘Class II’ ware. This type, in the light of extensive comparitive studies with securely dated material over the years, is now judged to be a Late Bronze Age coarse ware. Therefore the circle, officially designated to have been constructed in the Neolithic, is actually a Late Bronze Age site, of a similiar age to the axial stone circles that I felt had a comparable skeletal stucture (see fieldnotes above).
