A togher is a timber trackway built across bogland, constructed by laying brushwood, roundwood, and sometimes planks in a pattern dense enough to bear weight across otherwise impassable ground. This particular example was not merely a rough path but a carefully engineered crossing, its upper surface so densely laid that it would have offered stable footing for anyone travelling across the western reaches of the bog during its working life.

The togher runs east to west for 615 metres, leading from higher ground towards a dryland island at Dalysgrove. That directional logic tells you something about how medieval people moved through this landscape: bogland was not an obstacle to be avoided entirely but a territory to be threaded through, using islands of firmer ground as waypoints. The structure was built using transversely laid brushwood and roundwood elements, supported by longitudinal timbers running the length of the route, with lighter brushwood and twigs packed between and beneath. At one location, transversely laid planks were also recorded, suggesting a degree of variation in construction along its length. The togher ranges between 1.10 and 3 metres in width and between 1 and 57 centimetres in depth where it survives. Radiocarbon dating of recovered elements places its construction between 1410 and 1440 AD, firmly in the Late Medieval period. It was identified at thirty-seven separate sightings across the bog, visible both on the field surface and in the cut faces of drainage channels. At many of those points, industrial peat milling had already removed the upper walking surface, leaving only the damaged structural base below.
