Megalithic structure

The National Monuments Service's description

This feature, first shown on the 1849-50 edition of the OS 6-inch map, is to the N of Croaghan Hill in an area of rough terrain, the surface of which is rocky, uneven and strewn with boulders. It is prominently sited toward the northern end of a narrow ridge of bare rock and consists of a large slab resting on three low stones, which in turn lie flat on the rocky surface. The raised slab, which is c. 0.5m clear of the ground, measures 3.7m NNW-SSE by 2.3m wide at its southern end, narrowing to c. 1.5m at the northern end, and is c. 0.7m thick. The raised slab is tilted slightly from the horizontal, with the northern end a little higher than the southern end. This feature is not a megalithic tomb, but whether it is natural or artificial in origin is somewhat uncertain. Approximately 30m to the S there is a large boulder supported in a more or less upright position on some low stones, as if an attempt had been made to prop it up, and there is a similar feature a further 30m to the S. These are not megalithic tombs, although they have been listed as such in the SMR for County Donegal (1987).
