The sod-covered remains of a house foundation occupy the southeast corner of what may be a promontory fort, a type of enclosure in which a natural landform, here the jutting peninsula itself, does much of the defensive work, with an earthen bank or ditch closing off the neck of land to complete the enclosure. The date of the house is unknown, which places it in an awkward and interesting category: too eroded or too ambiguous to assign to a period, yet distinct enough in outline to be recorded and mapped.

The site was described between 1976 and 1981, when fieldworkers noted the square-shaped foundation inside the fort's interior alongside a second house site lying just outside the enclosure, immediately to the northeast. That pairing, one structure within the defended space and another just beyond its boundary, raises quiet questions about how the place was used and by whom, though the record does not press far enough into the evidence to answer them. The Breensford River runs approximately ninety metres to the south, and Killinure Lough connects this sheltered bay to the broader expanse of Lough Ree, one of the largest lakes on the River Shannon. Water, in other words, defines the setting on nearly every side.
