In the flat farmland around Ballynevin in County Tipperary, ringed by low hills, a circular earthwork once rose from the ground to a diameter of roughly thirty to thirty-five metres. Today there is nothing to see. The land has been worked flat, and whatever the feature once was, plough and time have removed it entirely from the visible landscape.

The earthwork appears on the Ordnance Survey six-inch map produced between 1901 and 1905, marked as a raised circular area sitting in what was then poor tillage ground. Circular earthworks of this general type in Ireland can represent a broad range of origins, from ring barrows used for prehistoric burial to the enclosed farmsteads known as ring forts, which served as the basic unit of rural settlement throughout the early medieval period. Without surviving physical evidence, it is impossible to say with certainty which category this one belonged to. What the map records is simply the shape, the size, and the fact that it was once there. The surrounding terrain, flat and agriculturally modest, would have made the raised outline relatively conspicuous in its day, which is presumably why a nineteenth-century surveyor thought it worth marking.
