(NM 3298 2098) Fort (NR)

OS 1:10,000 map, (1976)

Fort, Poit na h-I: On the summit of a rocky knoll 825m SE of Poit na h-I farmhouse, there is a fort known locally as Torr a' Chaisteil. The site lies in an extensive tract of broken country characterised by numerous granite knolls and ridges separated by fairly level, and often boggy, patches of ground. The flanks of the knoll are sheer rock-faces, 15m in greatest height, but by comparison the approach from the NW and SE ends is easy. The fort is defended by a single wall and, in order to enclose a large enough area, it has been built up to 6m below the general level of the summit, the internal area thus measuring about 50m from N to S

by a maximum of 40m transversely. For much of its circuit the wall is built on bare rock, and at numerous points the actual rock has been incorporated into the structure, with the result that the wall follows an irregular course in order to suit the configuration of the knoll. Considerable stretches of outer facing-stones survive, usually only the lowest course, but for a short distance near the entrance, on the SSE, five courses remain standing to a hieght of 0.9m. By contrast only two inner facing-stones can be seen, suggesting that the wall was about 2.5m in average thickness. On the NW several exceptionally large boulders have been included in the heavy rubble core-material. The entrance, 0.9m in width, is well marked, with the NE side-wall of the passage standing 0.9m high in three courses.

The interior is very uneven, a considerable amount of space being taken up by sheets of bare rock or by rock-bosses; the largest of the latter, situated in the NW quarter, rises 2.4m above the remainder.

Note (6 November 2014 - 23 May 2016)

Situated on a rocky knoll with precipitous flanks up to 15m high on the NE and SW, this fort measures about 50m from NW to SE by a maximum of 40m transversely within a single wall about 2.5m in thickness. Numerous runs of outer face are visible around its circuit and on the SSE adjacent to the entrance it stands 0.9m high in five courses; the facing of both sides of the passage also remains in place. The rocky and uneven interior is featureless.
