That is not an unusual situation for prehistoric sites, but there is something quietly striking about a place that exists, in the archaeological record, only as a faint disturbance in the earth.

The site sits in improved pasture roughly 300 metres west of Lough Gur, a lake long associated with one of the densest concentrations of prehistoric monuments in Ireland. In 2008, a geophysical survey of the area, specifically a fluxgate gradiometer survey, a technique that detects subtle variations in the magnetic properties of buried deposits, identified the feature as part of a broader investigation of the landscape around the Grange stone circle, which lies around 60 metres to the west. Two further stone circles sit in the adjoining field to the north, and a possible anomalous stone group has been recorded 35 metres to the south-east. What the 2008 survey, published by Cleary, identified as Feature 6 in Area 1 was described as a slender, semi-circular arc of negative magnetic gradient, approximately 12 metres in length and 0.5 metres in width. The surveyors suggested it could represent either the remains of a circular building defined by a stone wall footing, or a bedding trench whose fill happens to be less magnetic than the surrounding soil. No surface trace was visible on aerial photography taken between 2005 and 2012, nor on Google Earth imagery.

For anyone visiting the Lough Gur area, the famous Grange stone circle, one of the largest in Ireland, is the obvious and accessible focus. The field in which this buried anomaly lies is working agricultural land, and there is nothing to see at the surface. What the site offers, rather than a view, is a useful reminder that the visible monuments around Lough Gur almost certainly represent only a fraction of what the landscape once contained, and that the ground beneath the pasture is still, slowly, giving up its inventory.
