It is a togher, a term for the timber trackways that Bronze Age and Iron Age communities laid down across the soft, waterlogged ground of the Irish midlands, and this particular example is quietly remarkable for how well its age and construction have been pinned down.

The trackway was recorded in 1987 and measures sixteen metres in length, one metre wide, and just thirteen centimetres deep. It ran east to west and was built from longitudinal lengths of brushwood and roundwood, the individual pieces ranging from six millimetres to thirteen centimetres in diameter and between sixty-six centimetres and two and a half metres long. The method was practical and direct: timber laid flat and parallel across boggy ground to create a firm surface for crossing terrain that would otherwise have been impassable for people carrying loads or moving livestock. Radiocarbon dating placed its construction to between 1003 and 900 BC, a period in the late Bronze Age when Irish communities were active across these wetland landscapes, building dozens of such structures throughout the midland bogs. The dating result, given the laboratory reference GrN-15487, was published by Barry Raftery in 1996 as part of his wider work cataloguing Irish bog roads.
