Not a Roman road or a medieval cobbled way, but a togher, the Irish term for a timber trackway built across bogland, constructed from rounded beams of oak, ash, and birch laid side by side across the line of travel, then anchored into the soft ground with pegs of birch and hazel. At eight metres wide, this is no minor path; it is a substantial route, oriented WSW to ENE, built from materials that had to be selected, felled, shaped, and fixed in place by people who knew the bog well enough to move through it with purpose.

The togher at Leigh came to wider attention in the 1960s, when it was recorded by Rynne, who described its construction in detail: a brushwood and gravel track pinned down by wooden pegs roughly a metre long and four centimetres in diameter. The site sits on elevated bogland in County Tipperary, close to the early medieval ecclesiastical remains at Liathmore to the west, a proximity that raises quiet questions about who was travelling this way, and why. By 1995, when archaeologists from the Irish Archaeological Wetland Unit at UCD visited the site, peat milling operations were actively destroying it. The area contains further toghers in poor condition, including a brushwood and plank example just a metre wide, and a second of split planks oriented east to west, both fragile remnants of what was evidently a network of routes crossing this stretch of bogland rather than a single isolated track.
