Cahercommaun

Stone Fort

Cahercommaun Triple Stone Fort (stone fort of Comin) is dramatically situated on the edge of a cliff, all three of its concentric walls abutting the cliff edge. Built around 800 AD and remarkably similar to the great fort at Dun Aenghus on the Aran islands, the inner wall alone used 16,500 tons of stone and was almost a complete circle before the north wall fell down the cliff.

The two outer walls were connected to each other by subsidiary walls. The outer wall measures 350 ft East West by 245 ft North South. The second rampart or inner wall is 5ft thick and about 4ft high and around 30ft from the inner caher. The Fort was excavated in 1934 by the Harvard Archaeological Expedition which showed the enclosure had at least twelve stone buildings at varying times and a number of these had soutterrains.
In the top picture you can see the inner caher walls rising up to some 12 to 14 feet above the cliff. It is almost impossible to photograph such large forts from ground level. The drawing below best illustrates the size and layout of this amazing monument. Other sites of interest in this area include Cashlaun Gar, Creevagh, Poulaphuca and Parknabinnia. Other stone forts on this web site include Caherdooneerish.
