A togher is a raised wooden trackway, a practical solution to the problem of crossing the soft, treacherous surfaces of Irish midland bogs and wetlands. This particular example, recorded at Derryoghil, is modest in scale but precise in its construction: at least seventeen metres long, a metre and a half wide, and only about ten centimetres deep, running east to west through ground that would otherwise have been impassable.

The structure was first noted in 1987 and is classified as a class 2 togher, meaning it was built using a combination of longitudinal roundwood timbers laid along the direction of travel, larger twigs, and small wooden pegs hammered in to hold the whole assembly in place. The roundwood averaged around eight centimetres in diameter, the twigs rather wider, and the pegs were driven to depths ranging from twenty to fifty-five centimetres. There was little sign of elaborate woodworking on the material, suggesting the builders used relatively unprocessed timber, taking what the surrounding landscape offered. Radiocarbon dating has produced two date ranges for the structure: one placing it between roughly 1410 and 1131 BC, the other between 916 and 801 BC. Whether this reflects two distinct phases of construction, repair, or simply the natural variation within the organic material sampled is not entirely clear, but either way the trackway was in use during the Irish Bronze Age, a period when the midland bogs were actively crossed and managed by farming communities who left dozens of similar structures scattered across the landscape. The site is referenced in Barry Raftery's 1996 study of Irish bog roads, which catalogued many such finds from the wetlands.
