Giants Grave — Cool Beg

This tomb is c. 5km NNW of Ballyshannon in rolling pasture 500m from the coast. It stands c. 1.7km NE of the court tomb in Cloghbolie (Dg. 34). There is a good all-round outlook from the site, most notably westward to the sea. This monument has been incorrectly assigned to the adjoining townland of Cool More in much of the literature. The monument stands S of and immediately beside the cutting of an abandoned railway line. It consists of a gallery 7m long lying E-W and divided by jambs into two chambers, the inner one covered by a partly dislodged roofstone. There is a considerable fill of stones in the gallery. Two transversely set jambs, 0.7m apart, mark the E end of the gallery. A set stone outside the southern one may represent a doubling of the jamb. The northern jamb is 1.3m high, and the southern one is 1m high. The stone in front of the latter is 0.6m high. The eastern chamber is c. 3.3m long. Two orthostats, one large and the other small, both leaning inward, form its S side, but none is now visible on the N side, where an irregular drystone wall, 0.2-0.5m high, has been built. The largest stone in this wall, 0.7m long and 0.5m high, is shown on the plan. Outside the wall is a partly concealed prostrate slab, possibly a displaced sidestone. This measures 2m by 1.1m and is at least 0.4m thick. The eastern of the two sidestones at the S is 1.3m high, of similar height to the adjacent entrance jamb. Two thin slabs at its outer face have become detached from this orthostat. The outer one is 0.5m high, and the inner is 0.8m. The second orthostat on this side is set inside the line of the first, and its inner end is concealed. It is 0.4m high. Outside it is a prostrate slab 0.95m in maximum dimension. Two transversely set segmenting jambs, 0.7m apart, separate the chambers. The southern one, set inside the line of the gallery wall, rises 0.1m above the top of the adjacent large orthostat, which forms the S side of the second chamber. The northern jamb, partly inset in the gallery wall, rises 0.1m above the top of its fellow jamb. The inward-leaning southern sidestone of the western chamber is 1m high. Opposite this is a matching orthostat, 0.65m high. At the outer face of the E end of the last is a slab, apparently displaced, though in an upright position. This measures 1.3m by 0.25m by 0.6m high. The large roofstone overlying much of this chamber has slipped down the inner face of the southern sidestone and rests in a leaning position on top of the northern orthostat. It is 3.6m in overall length, 2.7m wide and 0.5m thick. This chamber was at least 3m long and narrows from 2.2m at the segmenting jambs to 1.85m at its open, western end. Thomas Fagan (1845-8) visited here in 1847, and his account shows that the monument was then in its present condition. It is clear that the roofstone of the western chamber had by then assumed its present somewhat dislodged position. An account in an OS Revision Name Book, written sometime between 1847 and 1849, mentioned 'a second covering stone' lying prostrate at the centre of the structure, but this is not now visible. Wakeman (1876-8a, 105) described this monument as a 'perfect example' of its class and claimed that the roof was intact. The earlier OS accounts, just referred to, suggest that Wakeman was mistaken about the roof. Allingham visited the site soon after Wakeman wrote about it and, finding it in its present state, concluded that it had been damaged only recently (Wakeman 1876-8b; Allingham 1879). There seems to have been a two-chambered gallery here, its front to the E. The narrowing of the western chamber toward the W end supports such an interpretation.
