This is a togher, the Irish term for a wooden trackway laid across wetland, and the example recorded at Corlea is a class 3 type, meaning it was a relatively modest construction rather than one of the great prehistoric plank roads for which this part of the midlands is famous.

What makes this particular scatter quietly compelling is the detail preserved in the wood itself. The timbers, predominantly alder, spread across roughly 1.4 metres in width and run on an east-north-east to west-south-west orientation. Alder was a practical choice for this kind of work; it resists decay unusually well when kept wet, which is precisely why it turns up so often in bog construction. Alongside the alder, there are damaged transverse hazel rods, the cross-members that would have been laid perpendicular to give the surface some grip and structure. More striking still are the metal toolmarks visible on the wood. These marks indicate that the togher was fashioned with iron tools, which helps narrow its likely date to the early medieval period or later, distinguishing it from the prehistoric plank roads nearby, some of which were built with stone and flint implements. Corlea is already well known for its extraordinary Iron Age trackway, dated to 148 BC, now partially preserved under the Corlea Trackway Visitor Centre a short distance away, so this quieter find sits in a landscape already layered with the evidence of people negotiating the same difficult terrain across many centuries.
