This one in Coolcaslagh, County Kerry, survives only as a circular shadow on a single aerial photograph taken in 1977, within a disused sand quarry where nothing now remains to be seen at all.

The photograph in question, taken as part of a national aerial survey programme, captured what appeared to be a small circular feature roughly five metres in diameter, sitting within a larger enclosure. A hut site of this kind would typically represent the ground-level trace of a simple round dwelling, the sort of structure common across early medieval Ireland, where low stone or earthen walls once defined a living space. The enclosure surrounding it, a bounded area of the kind often associated with farmsteads or small settlements, was also visible from the air. By the time any formal record was compiled, both features had vanished entirely, consumed or obscured by quarrying activity in the intervening years. There are no visible remains of either the possible hut site or its enclosure on the ground today.

What makes Coolcaslagh quietly affecting is precisely this completeness of absence. The site exists in the archaeological record because of a single image, a fleeting document of something that was already disappearing, in a field that is now just a worked-out quarry in Kerry.
