The enclosure on Ardaghlooda ridge does not appear on the six-inch survey of 1840, the twenty-five-inch edition of 1897, or the later Cassini revision. It took aerial orthoimagery, first captured between 2005 and 2012, to make it faintly legible again. That a structure of this kind could sit unrecorded for so long, in a landscape so thoroughly examined by archaeologists, is what makes it worth pausing over.

Ardaghlooda is a rocky ridge overlooking Lough Gur, one of the most intensively studied prehistoric landscapes in Ireland, and this enclosure is only one of three that survive on the hill itself. Archaeologist Grogan, writing in 1989, described it as a habitation enclosure, meaning a circular banked boundary that once defined a domestic or settlement space rather than a ceremonial one, roughly 25 metres in maximum diameter. Current measurements from satellite imagery put its external diameter at approximately 19 metres north to south and 17.5 metres east to west. The site pre-dates a later field system whose boundaries have since cut directly across it; one east-west field boundary bisects the enclosure entirely, which is part of why it is so difficult to read on the ground. The great stone circle at Grange, one of the largest of its kind in Ireland, lies 350 metres to the southwest. Standing stones are recorded nearby, and a further two enclosures sit within 100 metres on the same hill. Running along the western side of the ridge, roughly 100 metres from the enclosure, is a historic road known as Cladh na Leac.

The site sits on rocky pasture and is defined by a low bank that requires some patience to trace, particularly where the later field boundary interrupts it. Google Earth imagery from March 2016 and March 2017 offers the clearest overhead view of the circular form. Visitors to the Lough Gur area will find the ridge accessible on foot, though the ground is uneven and the feature is subtle enough that knowing its approximate location in advance makes a considerable difference. The surrounding density of monuments means that even a careful walk across Ardaghlooda will bring you past standing stones and traces of a field system that overlies these enclosures, layering era upon era in the same thin soil.
