A drystone walled structure with a doorway in its north west corner and constructed from stones varying in size from 10cmsq to 50cmsq. The northern facing wall reaches 1.5m in height but the others all show signs of collapse, reaching only about 0.5m high. All are approx. 0.5m thick. There is evidence of a collapsed roof as there are slate pieces of 1msq within the structure's wall. Noted during an upland survey conducted by Archaeophysica during 2005-6
