At Boolaglass in County Tipperary, on a north-west-facing slope in an upland stretch of countryside, there was once a rath, the Irish term for a ringfort, which was a circular earthwork enclosure used during the early medieval period, roughly between the fifth and twelfth centuries, as a farmstead and family settlement. Today, a silage pit and modern agricultural sheds occupy the ground, and nothing of the original structure is visible at surface level. The site exists now only in documentation, a name attached to a field where the past has been thoroughly overwritten.

Ringforts are among the most common archaeological monument types in Ireland, with an estimated forty to fifty thousand once scattered across the landscape. The one at Boolaglass would have been a modest enclosed homestead, its earthen banks marking the boundary of a farming family's world. Upland locations like this were not unusual; early medieval communities worked a wide variety of terrain, and a north-west-facing slope in North Tipperary would have offered reasonable grazing ground. The details recorded by Jean Farrelly and Caimin O'Brien in their archaeological inventory of North Tipperary, published in 2002, capture the site at a point when agricultural development had already erased whatever earthworks once defined it.
