Man-made underground passage in Cashelboy

Within the NE quadrant of a rath (SL018-028001-) are two hollows which may indicate a collapsed Man-made underground passage. The first is a linear depression (4m NE-SW; 2m NW-SE; D 0.65m) with stones protruding beneath the sod along its interior sides. The second is located 2m NE of the first, abutting the inner face of the bank. This comprises a roughly circular hollow (diam. 4m; D 0.4m) containing some sod-covered stone. Compiled by: Patrick F.
