Statement of Special Interest

Britain's most remote lighthouse, lying 40 miles west of Orkney and 37 miles NE of Cape Wrath. Its isolated position made it unsuitable for the accommodation of keepers' families; hence provision was made in Stromness (see separate list description). Designed and constructed by David Alan Stevenson, a member of Britain's foremost lighthouse engineering family, the Sule Skerry light answered a need for increased protection of the 'north-about' route around Britain, owing to additional congestion and resultant collisions in the English Channel. Although Sumburgh and North Ronaldsay were already lit, and the eastern side of Orkney being fairly well protected, the 160 miles of seaboard between the Pentland Firth and Muckle Flugga were dangerously unlit. Consequently, a series of important lights was built around the northern fringes of Britain - 2 on Fair Isle in 1892, Sule Skerry and Ratray Head in 1895 and the Flannan Islands in 1899. Sule Skerry island is fairly low lying, rising to 45 feet above high water, and is almost out of sight of land, the combination of these two factors necessitated the need for an extra-powerful light source on top of the 88 foot tower. To this end, lighting was delayed for a year after completion of the structure, while the Board of Trade and Trinity House argued with the Commissioners about the cost and character of the apparatus. As larger burners were used to increase the intensity of the light, they produced too much heat for the compact optical apparatus. As a result, the Stevensons increased the focal distance between the centre of the light source and the 'cage' of glass to 52 inches in what they called a 'hyper-radiant' apparatus. They also employed an arrangement of equi-angular prisms which caused less light loss and divergence than other types of lens. The lantern therefore required was larger than any previously designed for lighthouse service, being 16 feet in diameter instead of the normal 12. Stevenson's plans show how the lighthouse was divided internally; beneath the plinth was the water and provision store; the coal store was sited at the 1st stage, providing the all-important fuel to keep the lamps lit; a dry store was located above that, with the bedroom situated high, below the lamp room. With no accommodation structures outside the lighthouse, Stevenson provided a multi-bed chamber for the keepers within convenient reach of the lamp room. Plans show that three layers of paired bunks were stacked above two layers of paired drawers; a compact solution to manning a lighthouse with no accommodation block. Stevenson's plans also show the existence of fluted columns supporting H-girders in the lamp room. Now automated and unmanned.

About Designations

Listed Buildings

We list buildings of special architectural or historic interest and these are selected according to criteria published in the, Annex 2, pp74-76.

The information in the listed building record gives an indication of the special architectural or historic interest of the listed building(s). It is not a definitive historical account or a complete description of the building(s). The format of the listed building record has changed over time. Earlier records may be brief and some information will not have been recorded.

Enquiries relating to works to listed buildings should be made to the local authority in the first instance. Listed building consent is required for works which a local authority considers will affect its character as a building of special architectural or historic interest and local authorities also decide if listed building consent is required.

Listing covers both the exterior and the interior. Listing can cover structures not mentioned which are part of the curtilage of the building, such as boundary walls, gates, gatepiers, ancillary buildings etc. The local authority is responsible for advising on what is covered by the listing including the curtilage of a listed building. For information about curtilage see

Legislation introduced on 1 October 2015 allows us to state that: an object or structure fixed to the listed building; any object or structure within the curtilage of the listed building; and, any part or feature of the listed building that is not of architectural or historic interest may be excluded from a listing. If part of your building is not listed under the new legislation, the part will be excluded in the statutory address and in the statement of special interest. The statement will use the word 'excluding' and quote the relevant section of the Historic Environment Scotland Act 2014. Some earlier listed building records may use the word 'excluding', but if the Act is not quoted, the record has not been revised to reflect current legislation.
