Less than a metre long and barely a metre wide, this togher, as such bog roads are known in Irish archaeology, was constructed from brushwood laid both across and along its length, a simple but effective technique for creating a stable surface over soft, waterlogged ground. The method is older than any written record, and examples of it have been found across Ireland wherever people needed to move through wetland terrain.

The Baunmore togher was identified in 1995 by the Irish Archaeological Wetland Unit, based at University College Dublin, during a pilot survey of the Littleton Works. That survey was part of a broader effort to document the archaeological potential of Irish boglands before drainage and peat extraction could disturb or destroy what lay beneath. Toghers of this class, categorised by their construction method, are classified on a scale that accounts for complexity and material; brushwood roads like this one represent a functional, relatively low-effort approach, likely laid to serve a local and practical need rather than to connect distant settlements. The bog itself acts as a preservative, holding organic material in conditions that would see it rot away almost anywhere else, which is why a loose arrangement of branches cut perhaps a thousand or more years ago can still be examined and recorded today.
