(NH 3487 0695) Torr Dhuin (NAT) Vitrified Fort (NR) (Remains of)
OS 6"map, Inverness-shire, 2nd ed., (1904)

Surmounting Torr Dhuinn, or Torr Duin (R W Feachem 1963) , a rocky knoll whose E side is a 200' precipice, is a vitrified dun, with two possibly earlier outer unvitrified defences, protecting the N, W, and S arcs.
The dun is irregularly oval on plan, (T Wallace 1921) and measures c. 19.0m N-S by 10.0m within an overgrown vitrified wall c. 3.5m thick in the N where it is best preserved. No wall faces nor entrance are evident. A trench across the N half is probably an excavation trench. Outside the dun and enclosing the summit of the knoll are the poor remains of a wall which survives mainly as a terrace. A short stretch of wall core survives in the N and the discontinuous footings of the outer wall face can be traced in the N, W, and S arcs. Although there is some tumble below on the slope, the poor state of this wall suggests it has been robbed to build the dun. A gully leading up the slope in the SW is the entrance. It cuts through the line of the wall where its NW side is flanked by a line of earthfast stones, but its SE side is obscured and the width of the entrance is uncertain. Near the base of the knoll is a boulder-faced rubble wall with an entrance in the S. The inner face is visible for about 11.0m in the NW and one or two outer facing stones at this point give a wall thickness of 1.7m. A line of earthfast stones flanking the entrance suggests that here the wall increased to c. 3.0m. The other side of the entrance is mutilated and the width cannot be ascertained. Although Cotton (M A Cotton 1954) states that "traces of vitrification have been observed in this wall", only pieces that have fallen from the dun can be seen, and it is undoubtedly not vitrified. See 1:1250 enlargement. (OS (R D) 5 May 1964)

The outer face of the medial wall can also be traced in the E above the crags some 4.0m outside of and below the vitrified wall. Here are several large lumps of vitrifaction but these have probably dropped down from the dun wall. One stone on the W side of the entrance through the outer wall indicates an entrance width of 1.7m.

Drumnadrochit & Fort Augustus Local Plan, Oct. 1991: P13/2.39. Ancient Mons. & Archyl. Sites.

A topographic survey of the surviving vitrified stone walls and earthworks was carried out by Rubicon Heritage Services in 2014 on behalf of Forestry Commission Scotland. The purpose of the survey was to provide an enhanced baseline record of the upstanding remains at the site to inform future conservation and management of the monument. The results of the survey enabled the production of 3D digital terrain models. <1>
