The site is known as Killelton, or Cill Eilthín in Irish, and it holds the remnants of a modest oratory alongside two rectangular buildings, one of which presents a particular puzzle: its drystone walls survive to no more than 0.8 metres in height, and there is no clear evidence of an entrance anywhere along them.

The structure in question measures roughly 3.4 metres east to west and 8 metres north to south internally, and sits just 0.8 metres north of the oratory. An oratory, in the early Irish ecclesiastical tradition, was a small private or communal prayer house, often associated with a monastic enclosure or the settlement of a founding saint. The Cill element of the placename points to exactly that kind of early Christian foundation, and the overall layout, a defined enclosure containing a church and associated buildings, is characteristic of early medieval religious sites found across the Dingle Peninsula. The site was documented as part of the Corca Dhuibhne archaeological survey published in 1986, which catalogued the remarkable concentration of prehistoric and early Christian monuments along this stretch of the Kerry coastline.
