Archaeology Notes

NM94NW 5 c925 473.

Portnacroish (Karn Vain) - ? Clyde group chambered cairn: Though she could not locate it on the ground, Miss Henshall states that Karn-vain, visited by Pococke in 1760, must have been near Portnachroish (NM 925 473), not far from the shore of Loch Laich. Pococke describes an entrance in the cairn's W side, leading to a chamber 2 yds by 1 1/2 yds, and thence to another of similar size. N of this was another, with 3 entrances, and possibly two more, suggesting that the chambers had been built all round and in storeys.

A S Henshall 1972; RCAHMS 1975.

There is no local information on this cairn, and it was not located.

Visited by OS (DWR) 17 November 1971.


Field Visit (2006)

NM 925 473 In the summer of 2006 a search was carried out by the Appin Historical Society for the site of this chambered cairn, clearly described by Pococke and others in the 18th century as being on the N side of Loch Laich and opposite Castle Stalker. This must be close to Portnacroish and the only plausible remains found in this area consist of a flat rubble platform about 100m W of the row of houses, just before the road turns sharply NE and up a steep hill. The elongated platform is at least 30m long from NW–SE and only its SW edge is clearly visible (for about 33m) where the ground falls away. There are no visible traces of any large slabs which

might have been part of a chamber. The ruins of a stone cottage and its outbuilding stand on the platform.
