A togher is an ancient trackway built across wet or marshy ground, constructed by laying timber directly onto the surface of a bog to create a walkable path through otherwise impassable terrain. This particular example stretches 116 metres in length, measures 1.8 metres wide, and sits just 8 centimetres below the surface of the bog, an almost implausibly shallow burial for something that has endured so long.

The trackway runs on an east-northeast to west-southwest orientation and is classified as a class 2 togher, meaning it was built using a combination of transverse and longitudinal worked roundwood, in this case hazel. The use of hazel is telling. It is a fast-growing, flexible wood that was widely managed in early medieval Ireland through coppicing, a practice of cutting stems back to encourage regrowth, making it a reliable and renewable building material. The fact that the timbers were worked rather than simply thrown down suggests a degree of craft and planning, someone selecting, trimming, and laying each piece with intention. Bogs, by preserving organic material in their cold, oxygen-poor, acidic conditions, have kept thousands of such trackways across Ireland in extraordinary states of preservation, offering some of the most direct evidence we have of how people moved through the landscape in earlier centuries.
