Roads & Tracks
Beneath the bogland of Derrylough in County Longford, a narrow wooden road lies preserved in the waterlogged peat, built to carry people across ground that was otherwise impassable.
It is a togher, the Irish term for a trackway laid through wet or marshy terrain, and this particular example measures just over one and a half metres wide and roughly seventeen centimetres deep, modest dimensions that nonetheless required careful, deliberate construction.
The trackway is classified as a class 3 togher, meaning it was built using a combination of transverse and longitudinal roundwood, in this case ash poles averaging around six centimetres in diameter, interlaid with finer hazel brushwood averaging two centimetres across. Ash and hazel were practical choices, both being flexible, fast-growing, and readily available in the kind of mixed woodland that would have fringed Irish wetlands. The orientation runs northwest to southeast, suggesting it connected specific points across the bog rather than following its edge. A single worked peg was also recorded among the remains, a detail that points to deliberate joinery, the wood shaped by hand to hold the structure together rather than simply laid in place. The bog itself did the rest, its anaerobic, acidic conditions slowing decay almost entirely and preserving wood that might otherwise have vanished within a generation of being laid down.
