The remains consist of a ruined rectangular tower, some 6.7m N-S by 8.7m E-W, surviving at the NW corner some 11-12m high. There were originally three stories, the first horizontally subdivided by a wooden mezzanine floor; the ground and first floors were barrel-vaulted, while the other floors were of wood. Remains of a rock-cut ditch

survive 3-4m E of the tower; there may have been a continuation of this on the N and W, but if so it is now filled in.

The scheduled area comprises the tower and all above and below ground remains contained within an area extending for 6m from its walls on the NNW and WSW, and for 5m from its walls up to but not including the property appertaining to Castle House Cottage on the ENE, and up to the cliff edge on the SSE, measuring overall some 20m (E-W) by 15m (N-S).

Statement of National Importance

The castle is of national importance as a reasonably well-preserved tower-house with associated enclosure surviving in an island where such medieval remains are rare. As well as its architectural interest, the area around the tower is of great importance in affording opportunities for archaeological excavations which could tell us more about its outworks, the castle's periods of construction and occupation, and character of daily life enjoyed by its inhabitants.



RCAHMS records the monument as NS 02 SW 10.

About Scheduled Monuments

Historic Environment Scotland is responsible for the designation of buildings, monuments, gardens and designed landscapes and historic battlefields. We also advise Scottish Ministers on the designation of historic marine protected areas.

Scheduling is the way that a monument or archaeological site of national importance is recognised by law through the Ancient Monuments and Archaeological Areas Act 1979.

We schedule sites and monuments of national importance using the criteria published in the Historic Environment Scotland Policy Statement.

The description and map showing the scheduled area is the legal part of the scheduling. The additional information in the scheduled monument record gives an indication of the national importance of the monument(s). It is not a definitive account or a complete description of the monument(s). The format of scheduled monument records has changed over time. Earlier records will usually be brief and some information will not have been recorded. 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
