Roads & Tracks
In the boglands of Derrymany in County Longford, beneath layers of peat that have accumulated over centuries, lies the preserved remains of an ancient road built not from stone or gravel but from branches.
A togher is a trackway laid across wet or marshy ground, typically constructed from timber and brushwood to allow people and animals to cross terrain that would otherwise be impassable. This particular example is modest in scale, just 1.6 metres wide and roughly 12 centimetres deep, but its survival in the anaerobic conditions of the bog is precisely what makes it remarkable.
The structure runs on a northwest to southeast orientation and belongs to what archaeologists classify as a class 3 togher, a category defined by its use of longitudinal brushwood as the primary building material. The builders used slender rods and branches of ash, hazel, and birch, each between roughly 2.5 and 4.5 centimetres in diameter, laid lengthways along the trackway and reinforced at intervals with occasional transverse pieces set across the line of travel. The choice of species is telling: ash, hazel, and birch were all readily available in the wet woodland environments that would have fringed Irish bogland, and their flexible, relatively lightweight stems were well suited to this kind of laid-timber construction. Who built it, and when, the available evidence does not say, but toghers of this general type were in use across Irish bogland from the Bronze Age onward, representing a practical and long-sustained tradition of wetland engineering that demanded a close understanding of local materials and landscape.
