A ring-ditch, roughly circular in shape and about 8.5 metres across at its widest, lies mostly erased by centuries of ploughing, surviving only as a ghost in the soil. These features, shallow ditches that once encircled a burial or a monument of some kind, are common enough in the Irish archaeological record, but they rarely announce themselves. This one at Mweelra would have remained entirely invisible had it not been for a geophysical survey carried out in 2005, which detected the tell-tale fragmented linear and pit-type responses in the ground that betray a disturbed but still legible past.

The survey, conducted by Dr. Roseanne Schot, placed this small enclosure within a broader and evidently significant landscape. It sits in the south-western quadrant of a larger hilltop enclosure, roughly 70 metres south-west of a nearby mound. That relationship, a ring-ditch positioned close to an earthen mound within a hilltop complex, suggests this corner of Westmeath was once a place of some ceremonial or funerary importance. The ring-ditch itself has been so thoroughly reduced by agricultural activity that it no longer registers as a visible earthwork; what remains is essentially a pattern of buried anomalies, readable only through instruments that measure variations in soil resistance or magnetism.
