This is a togher, a type of wooden trackway built across boggy or marshy terrain to allow passage where the ground would otherwise swallow a traveller whole. The word itself comes from the Irish tóchar, and these structures appear across Ireland's midland bogs in varying forms, from elaborate plank roads to the most minimal of arrangements.

This particular example is classed as a Class 3 togher, meaning it is among the simpler varieties: a compact bundle of ash roundwoods, each up to roughly 0.186 metres in diameter, laid longitudinally along a northwest to southeast axis. The whole thing measures just 0.9 metres wide and 0.19 metres deep. Ash was a practical and widely available timber in early Ireland, valued for its strength and flexibility, and its use here suggests whoever built this road knew what they were doing, even if the scale is modest. The bog itself, by sealing the wood in cold, oxygen-poor conditions, preserved what would otherwise have rotted away centuries ago. Without that accident of hydrology, there would be nothing left to record at all.
