A togher is an ancient trackway laid across wet or marshy ground, essentially a timber platform engineered to carry people and perhaps animals across terrain that would otherwise swallow them whole. This particular example, a class 3 togher, survives in remarkable structural detail, its two layers of carefully arranged wood preserved by the very waterlogged conditions that made it necessary in the first place.

The construction follows a clear logic. A substructure of tightly packed ash brushwood and roundwood, pieces laid both lengthways and across, formed a stable base roughly half a metre deep. On top of this sat a superstructure of longitudinal hazel brushwood, seven pieces deep, oriented east to west across the bog. The trackway measured 3.5 metres wide, substantial enough to suggest it served more than foot traffic. Among the timbers recovered, one roundwood piece told a quieter story: its growth rings numbered more than fifty, indicating an unusually slow rate of development, the kind of thing that only becomes visible when wood is cross-sectioned and examined closely. A tree growing that slowly was likely doing so under difficult conditions, possibly in the shade of a dense woodland canopy or on poor ground. That a single piece of timber could carry such biographical detail gives some sense of how much information the bog has held onto, sealed away beneath centuries of peat.
