It appears on no historic Ordnance Survey Ireland maps, and for anyone walking the field it would be easy to miss entirely, the low enclosing bank barely distinguishable from the ordinary roll of agricultural ground. It is one of a cluster of up to eight possible barrows gathered into a single large field, something like 125 metres north to south and 175 metres east to west, a quiet concentration of prehistoric burial monuments that managed to remain off the official record for a very long time.

A ring barrow is, in simple terms, a burial mound of the prehistoric period defined by a circular bank and sometimes an internal or external ditch, typically associated with Bronze Age funerary practice. The Garrydoolis example came to formal attention through a Bruff aerial photographic survey carried out in 1986, recorded under reference Bruff 122.04 and AP 7/2028, when the site was identified from the air as a ring barrow. Aerial survey of this kind has been responsible for revealing a considerable number of Irish monuments that left no obvious surface trace legible to ground-level observers. Subsequent orthophotography taken by Ordnance Survey Ireland between 2005 and 2012 showed faint cropmark traces at the location, the kind of differential growth in vegetation that betrays buried or disturbed ground beneath. By November 2018, a Google Earth orthoimage was clear enough to show the circular form and its enclosing bank without ambiguity. The record was compiled by Martin Fitzpatrick and uploaded in April 2021.

Because the site lies in improved agricultural pasture, access would require landowner permission, and there is no formal public access or signage. The monument is most legible from above rather than at ground level, and a visitor expecting a dramatic mound would likely be underwhelmed by what they find on foot. The cropmark effect that helped confirm the site is most visible in dry summers, when soil moisture differences cause grass and crops above buried features to grow and colour unevenly. If you do have the opportunity to visit the broader area with the eight-barrow cluster in mind, the scale of what may be present beneath the field becomes more striking than any single feature: a prehistoric landscape of the dead, folded quietly into working farmland.
