The site at Garraí na Dtor was once a circular, univallate enclosure, meaning it was defined by a single earthen bank or wall, a form of boundary found across Ireland and commonly associated with early medieval settlement or stock management. It appeared on the second edition of the Ordnance Survey map, confirming it was still a visible feature of the landscape within the last two centuries. Today, a new house and its garden occupy the ground where that enclosure once stood.

The site sat directly south of the main Lispole to Dingle road, on a north-west facing slope above the valley of the Owenalondrig river. That orientation and position, looking out across a river valley, is a placement seen repeatedly in early Irish enclosures, where elevated ground offered both drainage and visibility. The enclosure was documented in J. Cuppage's 1986 archaeological survey of the Corca Dhuibhne region, a thorough examination of the Dingle Peninsula that catalogued hundreds of monuments across this exceptionally archaeology-dense stretch of west Kerry. This particular site was listed as entry number 687 in that survey.
