What was once a fort, the kind of roughly circular earthwork that dots the Irish countryside in its thousands, was levelled sometime around the late 1950s, taking the surrounding field fences with it. By the time archaeologists arrived to record it in 1987, they were essentially documenting an absence.

The Castleisland District Archaeological Survey visited the site that year and found pastureland at the foot of a ridge of high ground rising to the west, north-west, and north, with a stream to the east draining southward out of a narrow-sided valley. The setting, in other words, still carries the logic of why someone would once have chosen it: elevated ground nearby, water close at hand, a natural corridor to the north-east. A local man told the surveyors that the fort had been levelled roughly thirty years before their visit, placing the destruction somewhere around the late 1950s. No name for the individual or further detail was recorded, but that single reported recollection is now the closest thing the site has to a primary source.

Enclosures of this type, sometimes called raths or ringforts, were typically built during the early medieval period as enclosed farmsteads, their earthen banks defining a boundary between domestic space and the wider landscape. They were common enough that farmers across Ireland began clearing them through the twentieth century to improve agricultural land, a process that accelerated with mechanisation. What makes the Dooneen example quietly useful as a record is precisely that it was caught at the moment of disappearance, surveyed just late enough for the levelling to be recent memory but not so late that the memory itself had gone.
