The 1843 six-inch OS sheet shows a clear circular enclosure on the lower north-east-facing slope of a high ridge in County Tipperary; by the 1904 edition, it is gone. The site had been levelled in the intervening decades, the kind of agricultural erasure that happened to hundreds of such monuments across Ireland as land was cleared and worked more intensively.

A ringfort, or rath, is an enclosed farmstead of the early medieval period, typically dated to between roughly the fifth and twelfth centuries. They were built to a broadly standard pattern: a circular area enclosed by one or more earthen banks and ditches, used to protect a family and their livestock rather than to mount any serious military defence. The Lisgarriff example, though levelled, still holds its shape in the landscape. A circular area of approximately 23 metres east to west remains legible, defined by a bank about three metres wide and only around 0.4 metres high, with an outer fosse, that is, a ditch, of similar width running around it. The measurements are modest; this was never a large or elaborate enclosure. What makes it quietly notable is the persistence of its outline despite deliberate levelling, and the way the two OS maps bracket its destruction within a roughly sixty-year window.
