Roads & Tracks
In the bogland of Corragarrow, Co. Longford, a road has been lying quietly beneath the surface since somewhere between the late ninth and early eleventh century.
It is a togher, a type of timber trackway constructed across wet or boggy ground, and this particular example is classified as a class 3, meaning it was built from roundwood logs laid lengthways along the direction of travel rather than set crosswise like sleepers on a railway line. That longitudinal arrangement is what makes it structurally distinctive, and it is what the surviving timber still shows.
The togher first came to light during milling operations at the eastern shoulder of a drain, when four parallel roundwood timbers were exposed, each between seven and twelve centimetres in diameter, running NNE to SSW across the ground. A displaced piece lay in the base of the drain itself, and further roundwood and brushwood fragments of similar orientation were found on the field surface to the south-southwest, also being milled. At that stage, recorded in 1999, there was no visible evidence of woodworking on any of the pieces. Excavation carried out in 2002 changed that picture considerably. A run of closely spaced longitudinal roundwood was uncovered, extending over eleven metres in length and just over a metre wide, and this time the worked ends were clear: two timbers had been shaped to chisel points and one to a pencil point, the kind of deliberate tapering that would have helped drive or fix the wood into soft ground. Radiocarbon dating placed the construction somewhere within the period AD 894 to 1015, placing it firmly in the early medieval period, an era when such bog roads were a practical necessity for movement across the midland landscape.
