To the west of the summit of Galtymore lies a long dry stone wall known as the Galtee Wall, that was built in 1878 to separate the Dawson-Massey Estate in the north, from the Galtee Castle Estate in the south. It is recorded that it took 30-40 men more than 4 years to complete the wall, and that the reason for its construction was to give employment to local small farmers during a period of economic depression (hence why is it also called a famine wall). The Galtee Wall runs from below the west summit of Galtymore, across the top of Slievecushnabinnia, the top of Carrignabinnia, and on to the summit of Lyracappul, the second-highest peak in the Galtees.
