Roads & Tracks
In a bogland in Derrindiff, County Longford, the remnants of an ancient road survive in a form that is easy to miss and even easier to underestimate.
It is less than a metre wide, only a few centimetres deep, and built from thin branches of alder and hazel laid across wet ground. This is a togher, a type of ancient trackway constructed through boggy or marshy terrain by weaving or bundling brushwood, sometimes combined with heavier timbers, to create a surface that would hold a person's weight above the waterlogged earth beneath.
The Derrindiff togher is a class 3 example, meaning it belongs to a relatively modest category defined by its brushwood construction rather than the more elaborate split-plank or round-timber trackways found elsewhere in Ireland. The surviving material measures roughly 0.8 metres in width and about 0.07 metres in depth, composed of branches ranging from around two to four and a half centimetres in diameter. The species present, alder and hazel, are both characteristic of wet woodland margins and were the workhorses of ancient Irish wetland engineering, being flexible, widely available, and reasonably durable when kept permanently waterlogged. By the time it was recorded, the togher was in very poor condition, which is not unusual; these structures are fragile once the peat that has preserved them is disturbed or drained. The data was gathered by the Irish Archaeological Wetland Unit, a research body based at University College Dublin that systematically surveyed the boglands of the Irish midlands and west, recovering evidence of thousands of years of movement, labour, and landscape use from what might otherwise appear to be empty, featureless terrain.
