This neatly capped dry stone wall, standing roughly 1 to 2 metres tall by 1 meter wide at the base, extends for roughly 50 kilometres and connects 15 of the main peaks in the mountain range. It was originally built in the early 20th. century by the water supply authorities. This photograph was taken from the northern slope of Slieve Bearnagh looking across Hare's Gap towards Slieve Corragh.
