The monument consists of a dun or fort with broch-type features located on a knoll by the side of a steep valley. The massive wall of this structure is a maximum of 4.3m thick and stands to a height of at least 4m where best preserved. It forms the arc of a D-shaped enclosure 14m by 11.5m. The straight side of the D is along the face of a steep cliff. The main entrance is to the E, at the point of easiest approach. Traces of the N face of the entrance passageway and the door checks can be distinguished. There is also a second entrance, on the NNW, and traces of an internal wall chamber just to the E of this. In the interior there are traces of a sub- circular structure about 8m in diameter which appears to be later in date than the main structure. Outside the S and E are traces of two outworks protecting the monument on its most vulnerable approaches. The area to be scheduled measures 110m NNW-SSE by a maximum of 52m E- W, to include the dun, the outworks and an area around in which traces of activities associated with the construction and use of the monument may survive, as shown in red on the accompanying map extract.

Statement of National Importance

This monument is of national importance for its potential contribution to an understanding of prehistoric domestic life and architecture. This is one of the best preserved monuments of its type anywhere in Scotland. It appears to be a small fort rather than a broch, but includes broch-types features (wall chambers and entrance), and is of great significance for studies of the inter-relationship of the various categories of small drystone fortification.



The monument is RCAHMS number NG 81 NE 3.

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
