For generations it was known locally simply as a 'fort', which is a common enough term in rural Ireland for these early medieval enclosures, yet it never made it onto any official cartographic record. The earthwork measures about 26 metres in diameter, defined by a low, wide bank roughly eight metres across and just over half a metre in external height, with a wide shallow fosse, or ditch, of similar width running around it. The bank is more pronounced to the east and west, and the interior sits in a slightly concave depression, the whole thing worn down but still legible in the grass.

Ringforts, known in Irish as raths when defined primarily by earthen banks rather than stone, were farmstead enclosures built and occupied roughly between the fifth and twelfth centuries. Tens of thousands once existed across Ireland, and a great many were deliberately removed as farming practices changed over the centuries. The Condonstown example may be one of two ringforts recorded in the townland that a local historian named Power noted in 1917 as having 'been thrown down'. Power's account placed them somewhere in the townland but could not locate them precisely, leaving two catalogue entries unresolved. Whether this gently eroded earthwork in the pasture corresponds to one of those lost enclosures remains uncertain, but the coincidence of location and the degree of levelling makes it a plausible candidate. That it survived at all, even in reduced form, is somewhat surprising given how thoroughly the surrounding landscape appears to have been worked over.
