Not a road in any sense most people would recognise, but a togher, an ancient trackway built from timber laid across wet ground to allow people and animals to cross terrain that would otherwise have been impassable. This particular example, recorded at Derrindiff, is a modest one, less than a metre wide and barely eighteen centimetres deep, running east to west through ground that has preserved it long after the people who used it are forgotten.

The structure belongs to a category known as a class 3 togher, which indicates a relatively simple form of construction. Rather than the carefully hewn planks or neatly jointed timbers found in more elaborate bog roads, this one is made from brushwood and roundwood, the kind of material cut from small branches and young trees, with an average diameter of around five centimetres. The pieces were laid longitudinally, meaning along the line of travel rather than across it, and the overall arrangement is described as having poor structural definition, suggesting the timbers were not placed with great precision or have shifted considerably over time. Toghers of this kind are found across the Irish midlands, where bogland was both an obstacle to movement and, paradoxically, the very environment that ensured wooden structures survived for centuries or even millennia. The Irish Archaeological Wetland Unit, based at University College Dublin, recorded many such features during systematic surveys of these landscapes before drainage and turf-cutting could erase them entirely.

What survives at Derrindiff is less a monument than a trace, a faint structural memory of routine movement across difficult ground. Its dimensions are small enough that it might have served a single farm or settlement, a practical solution to a local problem rather than any kind of thoroughfare. The brushwood and roundwood it was built from were the most readily available materials in such an environment, and their use here suggests a pragmatic, unlaboured approach to the problem of getting from one place to another without sinking.
