The monument comprises the remains of a partially-excavated broch. The monument was first scheduled in 1938 but an inadequate area was included to protect all of the archaeological remains. The present rescheduling rectifies this.

The monument is situated on a partly artificial peninsula on the E side of Loch Rangag. It survives as a turf-covered mound approximately 20m in diameter and 4m in height. A guard chamber is visible on the N side of the debris-filled entrance passage in the E. Part of a mural chamber is visible in the NW. On the landward side of the peninsula is a heather-covered stone bank approximately 1m in height and 3-4m wide, extending N-S for a distance of 26m. About 11m from the N end of the bank is a gap with a turf-covered causeway extending from it across the isthmus to terminate on the broch. However, the causeway is off-set from the broch entrance and may not be contemporary with the broch. Stonework is evident extending into the loch for a distance of several meters.

The area to be scheduled is a circle 55m in diameter centred on the centre of the broch to include the broch and an area around (including under water) in which evidence relating to its construction and use may survive, as marked in red on the accompanying map.

Statement of National Importance

This monument is of national importance as the remains of an Iron Age broch which the partial excavation demonstrates has the potential to provide information on the nature of settlement and defensive architecture during this period of prehistory. Significant archaeological remains - perhaps some waterlogged - will survive in and around the broch.



The monument is recorded by RCAHMS as ND 14SE 4.


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
