Roads & Tracks
Beneath the bogland of Derrindiff in County Longford, two ancient roads were laid one on top of the other, a quiet accident of preservation that says a great deal about how people have been crossing wet ground in Ireland for thousands of years.
The lower of the two is a togher, the Irish term for a trackway built through marsh or bog, and it survives as what may be a hurdle panel: a woven section of brushwood laid flat to create a firm, if modest, surface across otherwise impassable terrain.
The panel measures roughly a metre wide and fifteen centimetres deep, oriented on a northwest to southeast alignment. It is made from thin rods of hazel and alder, each between one and a half and three centimetres in diameter, arranged transversely, meaning laid across the direction of travel rather than along it. This is the defining characteristic of a hurdle-style togher, where woven or bundled branches act almost like a raft, distributing weight across soft ground. Hazel and alder were the practical choices of ancient Irish road-builders; both grow readily in wet conditions and, crucially, alder resists decay when kept waterlogged, which is largely why examples like this survive at all. Directly above this lower structure lay a second togher, a separate construction phase recorded independently, suggesting that this particular route across the bog was used, abandoned, and then used again, with later travellers perhaps unaware of what lay just beneath their feet.
