Drumanoo Stone Ringfort and Man-made underground passage

Internal diam. 15.2m N-S, 16.9m E-W. A subcircular area enclosed by a collapsed stone wall originally c. 2.2m in width and up to .56m in height. In some places inner and outer wall facing up to three courses in height is preserved. A largely filled-in Man-made underground passage (DG097-032002-) occurs in the SE sector of the interior. It is orientated ENE-WSW. It is evident as a depression on the surface 5.1m in length widening from .85m to 2m in width at its WSW end. One roof slab is visible in this depression. The width of the top of the sou-terrain beneath is 1.1m. The ENE end of the souter-rain may have run under the cashel wall. Encircling the cashel wall at a distance of 21m on the N side is a discontinuous wall or setting of stones. This is 6m to 7m below the level of the cashel wall. The site is located on a height with commanding views and rock outcrop. The above description was derived from the 'Archaeological Survey of County Donegal.
