Full Description

A dun (noted by Cameron {1954} as a fort, and also traditionally the site of a castle) on a knoll on Dun Ghallain, a rocky islet only accessible at low water.
Its shape conforms to the summit of the knoll and it measures c. 16.0m N-S by c. 11.0m within a ruinous stone wall. Both inner and outer wall faces can be seen occasionally, the latter surviving to a maximum height of three courses, giving a wall thickness varying from 1.4m in the NE to 3.4m at the entrance in the SW, which is at the easiest point of access. Part of the base course of the N side of the entrance passage is visible. The dun is protected by crags on all sides but the W and here, at the base of the knoll, two or three stones suggest that there may have been a wall protecting the approach, but it is too obscured by tumble and grass to be certain. Outside the entrance is a natural platform with traces of a wall along its S side which has blocked a gap in the crags. Within the dun are the footings of a rectangular building oriented E-W and measuring c. 3.2m x 2.0m within a wall 0.8m thick. Its SW corner appears to overlie the dun wall although this is not too clear; otherwise it is in the same state of preservation as the dun. Surrounding the knoll are the remains of a crude wall of boulders laid haphazardly on a rocky scarp. It may have constituted an animal enclosure associated with the dun.

Below the crag in the SE, a midden of limpet and scallop shells, bones, and a few small pieces of mortared stnes, has been exposed. The mortared stones may be from the rectangular building although none can be seen in its structural remains.
Surveyed at 1:10,000.

Dun, Dun Ghallain: This dun occupies the summit of the rocky knoll that forms the highest part of a small tidal island lying off the N shore of Loch Sunart. The sides of the knoll rise as cliffs up to 7.6m high except on the W, where there is reasonable access up a steep rocky slope.
Irregular on plan, the dun measures about 13m by 11m internally, the wall following the outline of the summit of the knoll. Considerable stretches of both inner and outer facing-stones are visible, the outer face standing to a maximum height of 1m in three courses. On the NW, at the one point where it can be measures, the wall is 2.1m thick, but it was probably thicker on each side of the entrance, which is situated on the WSW. Partly overlying the wall on the SE are the foundations of a rectangular enclosure of no great age.
Round the base of the knoll there is an outwork consisting partly of very large boulders dragged roughly into line to form a crude obstacle, and partly of stretches of rubble resembling the remains of the core material of a boulder-faced wall. Each of the two gaps in the outwork, situated on the NW and NE respectively, appears to be an original entrance.

A rectangular bone object, apparently a stage in the manufacture of bone beads, from a kitchen midden at Dun Ghallain, was donated to the NMAS in 1974-5 by Mr I Thornber, Ardtornish.

A dun has been built on this island accessible only at low tide. The dun encloses an area c16m by 11m. This has been a desk assessment area.
