Looking at the Canmore record for Cairn Holy 2, they publish extracts from a Publication Account from 1986 (Exploring Scotland's Heritage: Dumfries & Galloway) which I found interesting: "On their hillside setting above Wigtown Bay, these two chambered tombs possess a range of dramatic visual qualities that are apparent under all lighting conditions. The lower or southern cairn (Cairnholy I) is quite majestic with its pillared eastern facade; set on a knoll some 150m to the north, Cairnholy II is not so grand but its portals and inner capstone give it a more mysterious aspect. These tombs are the best of the Clyde group of long cairns in the region, and their excavation in 1949 produced a rich assemblage of finds ..... The cairn which originally covered Cairnholy II has been much denuded, leaving only its irregular oblong outline around the summit of the hillock. Most of the stones evidently went into the construction of dykes and buildings in the late 18th century, but robbing stopped at the large slabs of the tomb itself. It consists of slab-sided inner and outer (perhaps secondary) chambers, the inner still retaining its large capstone. The entrance is flanked by tall and leaning portal stones, one 2.9m high, the other possibly broken; like Cairnholy I, it had a large closing stone, now recumbent Excavated frnds from the outer compartment included a leaf-shaped arrowhead, a flint knife and Beaker pottery, thus showing a similar range of users to that of the neighbouring tomb."
Something is not right. This message is just to keep things from messing up down the road
