Description

The monument is a broch dating probably from the Iron Age (between 600 BC and AD 400). The monument is visible as a roughly circular mound, measuring around 40m NNW-SSE by 35m WSW-ENE and standing up to 3m high. The mound sits on top of a wider platform or sub-rectangular mound, measuring approximately 45m NNW-SSE by 40m WSW-ENE. Known locally as 'the castle', the mound is expected to contain the foundations of a substantial broch tower, similar to the Broch of Burrian some 525m to the NNE. The monument is located in an area of unimproved, relatively level ground E of the Loch of Harray, at about 15m above sea level. It has extensive views in all directions, but especially to the W and S over the Loch of Harray. The monument was first scheduled in 1937, but the documentation did not meet modern standards: the present rescheduling rectifies this.

The scheduled area is circular on plan, 55m in diameter, to include the remains described above and an area around them within which evidence relating to the monument's construction and use is expected to survive, as shown in red on the accompanying map. The scheduling specifically excludes the above-ground elements of the post-and-wire fence and a water trough. It also excludes the top 300mm of the surface of the track and passing place to the SE to allow for their maintenance.

Statement of National Importance

This monument is of national importance because it has an inherent potential to make a significant addition to our understanding of the past, in particular of Iron Age society in Orkney and the function, use and development of brochs. By analogy with excavated brochs in Orkney, this monument is likely to retain its structural characteristics to a marked degree and may have a complex development sequence. Its importance is enhanced by its proximity to several other brochs in the Loch Harray area, especially the Broch of Burrian, with high potential to study the relationship between them. The monument is part of a landscape containing an exceptional concentration of important archaeological sites testifying to social and economic change over several millennia. The loss of the monument would significantly diminish our future ability to appreciate and understand the development, use and re-use of brochs, and the nature of Iron Age society, economy and social hierarchy in Orkney and further afield.

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 www.historicenvironment.scot.
