This one, in the townland of Boolavoord in County Limerick, survives partly in the landscape and partly as a ghost visible only in aerial photography, its outline captured in Digital Globe imagery long after the earthworks themselves were compromised.

When recorded by O'Kelly in 1942 and 1943, the site was already damaged. The description noted that roughly one-third of the eastern side had been levelled, though enough remained to establish its basic form: a circular platform edged by a bank, with an overall diameter of around 200 feet, or 61 metres. No fosse, the defensive ditch that typically accompanied such banks, was visible at the time of survey. Ringforts, known in Irish as raths when defined by earthen banks rather than stone, were the most common form of rural settlement in early medieval Ireland, generally dating from roughly the sixth to the twelfth centuries. They functioned as enclosed farmsteads, the bank and any accompanying ditch providing a degree of security for people and livestock rather than any serious military fortification. That the fosse here was already invisible by the 1940s suggests either that it had been filled in deliberately or had simply silted and grassed over across the preceding centuries.

For anyone making their way to Boolavoord, the site rewards patience and a willingness to look carefully at the ground rather than expecting a dramatic earthwork. The surviving platform and remnant bank are what remain after the levelling of the eastern arc, so the circuit is incomplete. Consulting aerial imagery before visiting helps orient the eye to what the field is actually holding. The monument was uploaded to the record in February 2020, compiled by Caimin O'Brien, which means it is formally documented but not necessarily signposted or managed as a visitor site.
