The Shell Guide to Ireland (1967), and Harbison's Guide to the National and Historic Monuments of Ireland (1992) also refer to the monument as a "stone circle." According to "TomFourwinds," (Megalithomania) the confusion may have originated with the 1840 OS maps. where the monument was labeled "Stone Circle."
