Description edit
The fort is situated on a narrow ridge, at height 365 metres (1,198 ft). It is an elongated enclosure, length about 216 metres (709 ft) and width 58 metres (190 ft), orientated north-east to south-west, aligned with the ridge.[1][2]
There is a rampart enclosing the inner area, with a steep slope to the south-east and ditches and counterscarps elsewhere. The principal entrance is in the north-east. The fort was enlarged: there is a bank, formerly the south-west end, traceable across the interior, and further defences were built to the south-west, notably a large rock-cut ditch and a rampart built with the stone from the ditch.[1][2]
The sites of about 25 round huts, diameter 15–20 feet (4.6–6.1 m), have been detected, mostly in the later part of the enclosure.[1][2]
There are some burnt stones in the south-west corner, but this is not thought to be evidence of a connection with the vitrified forts of Scotland.[1][2]
