Fort and Cave — Creggan (stranorlar Ed)

In a ringfort (DG068-022001-) which was levelled in the past. This souterrain is indicated as ‘Cave’ on the 1837 OS 6-inch map, but is not indicated on later editions. It consists of three interconnected chambers, each constructed with drystone walls and roofed with large slabs. In parts, it is built on bedrock. The souterrain as a whole extends for c. 14m in a gentle arc from SW−N−SE. A collapsed section of roof allows access into the SE chamber (L 2.7m; Wth 2.1m; H 1.6m), which is subrectangular in plan. In this chamber there are two short transverse lengths of roughly built walling, constructed to support the roof. A short creepway at the W end opens into the E end of the second chamber or passage (5.5m; Wth 0.75m; H 1.6m), which is noticeably narrower and longer. At the W end of this chamber, a short creepway leads to the E end of the third chamber (L 4.6m; Wth 1m; H 1.6m), which is oblong in plan. The floor of this chamber is covered with a layer of large stones topped with a thin layer of smaller stones. Over twenty circular depressions/cupmarks were noted on a roof slab (c. 2m by c. 1.3m) in the SE chamber, and three similar, but faint, depressions on a roof slab in the middle chamber; it is unclear whether the depressions are natural or artificial in nature.
