‘This is a detail of the Iron Age trackway, or “togher”, at Corlea, near Keenagh, Co. Longford. The trackway is built of oak planks with pins to hold each plank in place. It was discovered during peat extraction by Bord na Móna in the 1980′s and subsequent excavation and dating gave a date for circa. 148BC. The exposed length of trackway is in situ and housed in an interpretive centre.’. Photo by Ciarán Davis.
