These structures are among the more quietly remarkable survivals in the Irish archaeological record. Bogs preserve organic material with unusual fidelity, and toglhers that would have rotted away centuries ago in drier ground can emerge from peat cuttings looking almost freshly laid. The Kilmacshane example is classed as a class 2 togher, a designation that refers to its method of construction, typically involving split or roundwood timbers arranged transversely across the line of travel, forming a corduroy-like surface over the wet ground.

Toglhers were built across many centuries in Ireland, from the Neolithic period through to the early modern era, and they speak to how communities negotiated a landscape that was, for much of the year, actively hostile to movement. Galway's midland bogs were no different, and a togher of this kind would have served a practical, everyday purpose, linking settlements, grazing grounds, or routeways that drier land could not connect directly. The specific history of the Kilmacshane togher, including its date of construction, the timbers used, and how it came to be recorded, remains to be fully documented, but its classification places it within a well-understood tradition of Irish wetland engineering that stretches back thousands of years.
