Summary

This fort cuts off a precipitous promontory at the foot of the NW face of Creag a' Chaisteil on the S shore of Calgary bay. The approaches from the S and E along the terrace taken by the public road are cut off by a single wall forming a band of rubble about 3m thick and 0.6m high, but excavation in 1964 showed that it is 2.1m to 2.4m in thickness. The interior measures about 73m from N to S by 36m transversely (0.18ha), and there are entrances on the SSW and SSE, both of which were also excavated. That on the SSE was paved and had the door at the inner end of the passage, whereas that on the SSW had been inserted, and reduced in width from 3m to 1.3m in a secondary phase (Betts 1964). The terrace outside the defences and the interior have both been cultivated during the post-medieval period, but the excavations located an oval structure with an earthen floor and timber posts immediately within the SSE entrance.
