It is a togher, an ancient trackway built across wet or marshy ground by laying down timber, branches, or other organic material to create a passable surface where the ground would otherwise swallow a traveller whole. This particular example is classified as a class 3 togher, meaning it is a relatively modest construction, just 1.18 metres wide and only around six centimetres deep, made from a thin spread of hazel and birch brushwood laid in a northwest to southeast orientation.

What makes toghers quietly extraordinary is the combination of their simplicity and their survival. Brushwood laid directly onto boggy ground would rot away to nothing in most environments, but the waterlogged, oxygen-poor conditions of an Irish raised bog act as a preservative, holding organic material in a state of suspended decay for centuries or even millennia. Hazel and birch, both native Irish species that would have been readily available and easily cut, were the materials chosen here, probably selected for their flexibility and abundance rather than any particular engineering virtue. The resulting structure was never intended to be monumental. It was a practical solution to a practical problem, a way of crossing ground that could not otherwise be reliably crossed. Thousands of such trackways once stitched together the wetland landscapes of the Irish midlands, connecting settlements, fields, and pastures across terrain that shifted with the seasons.
