It cannot be seen, it cannot be walked, and there is nothing on the surface to mark where it lies. Its existence is known only because someone, at some point, found it ten feet down.

A togher is an ancient trackway or road built across boggy or waterlogged ground, typically constructed from timber planks, brushwood, or bundles of organic material laid across the soft terrain to create a passable surface. Such structures were often built during the early medieval or prehistoric periods, when bog roads were a practical solution to the challenge of crossing Ireland's extensive wetlands. The one at Cooleeny was recorded in topographical files held by the National Museum of Ireland, based on a reference from 1973. At that time, it was noted as lying roughly ten feet below the surface of the bog. No above-ground trace has ever been identified.

Bog environments are remarkable preservers of organic material, and toglhers found elsewhere in Ireland have survived in extraordinary condition, with timbers still intact after thousands of years. Whether the Cooleeny example survives in similar condition is unknown. It remains, as far as the available record is concerned, an unexcavated and largely undocumented feature; present, presumably, but invisible and inaccessible to anyone standing on the ground above it.
