A togher is a bog trackway, typically constructed from timber laid across wet or unstable ground to allow passage, and the examples at Lurgoe represent some of the more quietly remarkable prehistoric engineering to survive in this part of the country. What is particularly striking here is not just their age but their purpose: these were not incidental paths but deliberate connections between specific places, linking the bog islands of Derrynaflan and Derrynabrone across otherwise impassable terrain.

At least four such toghers were identified in 1987 by Raghnall Ó Floinn, brought to light not by archaeological excavation but by peat-milling operations working through the bog. They lay approximately 1.1 metres below the surface. One was subsequently excavated and found to be around a metre wide, constructed from branches of ash or hazel, each up to four metres long and between four and sixteen centimetres thick, laid in a single layer and pinned in place by vertical posts set half a metre apart. The method is economical and practical, making use of locally available timber in a way that has kept the structure recognisable across millennia. Pollen analysis pointed to a prehistoric date, most likely the Bronze Age, suggesting these paths were in use well before the early medieval church at nearby Derrynaflan became the focus of the landscape. Scattered traces of further trackways are still visible on the bog surface today, the buried network hinting at a pattern of movement and settlement that the peat has largely swallowed.
