The structure is classified as a togher, the Irish term for a timber trackway built across boggy or marshy terrain. This particular example is modest in scale, just over a metre wide and roughly a quarter of a metre deep, and runs on a north-north-east to south-south-west axis. It belongs to a class 3 designation, indicating its construction from brushwood rather than split planks or heavier timber. The Irish Archaeological Wetland Unit, based at University College Dublin, came across it in 1995 during a pilot survey of the Littleton Works, a peatland area that has yielded evidence of ancient human movement through what would once have been an impassable landscape. Toghers of this kind are significant precisely because the anaerobic conditions of bogs preserve organic material that would rot away almost anywhere else, leaving behind rare physical traces of how people once negotiated the Irish countryside before roads of stone or gravel were a possibility.
