A togher is an ancient trackway laid across boggy or waterlogged ground, constructed from timber and brushwood to create a passable surface where there would otherwise be none. This one is a substantial piece of work: over four metres wide and nearly half a metre deep, running on a north-north-west to south-south-east axis through ground that would have been difficult, perhaps impassable, without it.

The construction technique is specific enough to tell a quiet story about the people who made it. The main body of the trackway is a dense mat of ash and hazel brushwood, the individual stems ranging from roughly two and a half to three and a half centimetres in diameter, laid in a tight and deliberate arrangement. Larger ash roundwood, some up to about eleven and a half centimetres across, sits on the upper surface, presumably to provide a firmer footing. Most significantly, toolmarks were found on the timber, meaning that the wood was not simply gathered and laid; it was cut and shaped. Someone prepared these materials with an implement, gave thought to the task, and built a road meant to last. The togher was recorded by the Irish Archaeological Wetland Unit, based at University College Dublin, as part of broader efforts to document the extraordinary quantity of ancient wooden structures that Ireland's bogs have kept intact over millennia.
