The monument consists of a vitrified fort which occupies the sloping summit of a hill on the W flank of Glen Nevis.

The fort is roughly pear-shaped on plan. Its internal measurements are about 46m ENE-WSW by about 27m at its widest in the WSW and about 11m at its narrowest in the ENE. It is defined by a ruinous stone wall which is spread to a maximum width of 8m and survives to a maximum height of 2.5m. The wall contains numerous fragments of vitrified rock. The interior slopes down from E to W and in the E there are 2 stony scarps defining 2 level platforms. The entrance is on the W and is marked by a gap in the wall at its lowest point. Faint traces can be seen of a path running up the NW slope of the hill to the entrance. At the base of the N slope there is a circular depression about 4m in diameter and 0.5m deep. This would appear to be a well or cistern. Fragments of the vitrified rampart litter the N slope of the hill between the fort and well.

The area to be scheduled measures 125m NNW-SSE by a maximum of 95m WSW-ENE, to include the fort, tumble from its vitrified rampart, the well and an area around in which traces of activities associated with the construction and use of the fort may survive, as shown on the accompanying map extract.

About Scheduled Monuments

Historic Environment Scotland is responsible for designating sites and places at the national level. These designations are Scheduled monuments, Listed buildings, Inventory of gardens and designed landscapes and Inventory of historic battlefields.

We make recommendations to the Scottish Government about historic marine protected areas, and the Scottish Ministers decide whether to designate.

Scheduling is the process that identifies, designates and provides statutory protection for monuments and archaeological sites of national importance as set out in the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments that are found to be of national importance using the selection guidance published in Designation Policy and Selection Guidance (2019)

Scheduled monument records provide an indication of the national importance of the scheduled monument which has been identified by the description and map. The description and map (see ‘legal documents’ above) showing the scheduled area is the designation of the monument under the Ancient Monuments and Archaeological Areas Act 1979. The statement of national importance and additional information provided are supplementary and provided for general information purposes only. Historic Environment Scotland accepts no liability for any loss or damages arising from reliance on any inaccuracies within the statement of national importance or additional information. These records are not definitive historical or archaeological accounts or a complete description of the monument(s).

The format of scheduled monument records has changed over time. Earlier records will usually be brief. Some information will not have been recorded and the map will not be to current standards. Even if what is described and what is mapped has changed, the monument is still scheduled.

Scheduled monument consent is required to carry out certain work, including repairs, to scheduled monuments. Applications for scheduled monument consent are made to us. We are happy to discuss your proposals with you before you apply and we do not charge for advice or consent. More information about consent and how to apply for it can be found on our website at
