Roads & Tracks
In the boglands of Derrindiff in County Longford, what survives of an ancient road amounts to three thin poles of ash and hazel laid side by side across wet ground.
That is it. Sixty centimetres wide, seven centimetres deep, oriented east to west, this is a class 3 togher, and its very modesty is what makes it worth attention.
A togher is a timber trackway laid across boggy or waterlogged terrain, a type of construction found across Ireland from the Neolithic period through to the early medieval era. They range from elaborate multi-layered platforms of planks and pegs to the simplest of solutions: a few roundwood poles placed longitudinally to give a traveller's foot something firmer than peat to land on. This example belongs firmly to that simpler tradition. The three roundwoods, each averaging around six and a half centimetres in diameter, were cut from ash and hazel, both common native species and both well suited to the kind of light, workable timber needed for a structure that had to function in saturated ground. At class 3, this is among the most basic forms of togher recorded, essentially a minimal intervention in difficult terrain, engineered just enough to make passage possible. The bog that once made such a crossing necessary has also been responsible for preserving it, the anaerobic, waterlogged conditions slowing the decay that would long since have consumed timber left on dry land.
