It is a togher, the Irish term for a timber trackway laid across soft or waterlogged ground, and this particular example is modest in scale but quietly precise in what it reveals about the people who made it.

The trackway is just under a metre wide, at 0.97 metres, and survives to a depth of 0.14 metres. It runs on a northeast to southwest orientation and was constructed primarily from longitudinal brushwood, thin rods of hazel and birch averaging around three centimetres in diameter, laid lengthways to form a firm surface across ground that would otherwise have been impassable. Occasional roundwoods appear alongside the brushwood, and what survives shows clear signs of deliberate woodworking, meaning the timber was shaped or prepared before being laid, rather than simply thrown down. Hazel and birch are both fast-growing species well suited to this kind of construction, coppiced repeatedly to produce straight, workable rods, and their presence here points to a community that understood its local woodland and managed it with some intention. The bog, paradoxical as it seems, is what saved all of this. Waterlogged, oxygen-poor conditions suppress the microbial activity that would otherwise rot organic material, leaving wood that might be thousands of years old still recognisable in cross-section and grain.
