North Ronaldsay is the northernmost island in the Orkney archipelago of Scotland.
History
Old Beacon
The ‘Old Beacon‘ now a grade A listed building was the third lighthouse to be built by the Northern Lighthouse Board. The tower was constructed by stonemasons brought in from Leith, Edinburgh and its light was first lit on 10 October 1789. Thomas Smith, an Edinburgh Lamplighter, was the engineer for the light, assisted by his stepson Robert Stevenson. The 70ft tower was built using local undressed stone, as was the nearby lightkeepers cottage. The bill for the two masons John White, and James Sinclair was £199-2-6d.
Its light, advanced for the time was the catadioptric, or reflecting system, which consisted of a cluster of lamps burning oil, with copper reflectors. The reflectors were cleaned with a soft linen rag and Spanish white or finely powdered chalk until there were perfectly bright. These instructions were to be strictly adhered to, or a great part of the effect of the light was lost,
Smith chose to build the first North Ronaldsay tower at Kirk Jaing, the most easterly point of The bill of the mason’s work came to £199-12-6d.
In 1806, a lighthouse was built at Start Point, and North Ronaldsay, then considered redundant, was extinguished in 1809. Its lantern was replaced by a great wall of masonry removed from Start Point in 1806. It still survives as a great unlit beacon, its sturdy walls a tribute to good masonwork.
New Lighthouse
As the years passed, it became obvious that this island, with its dangerous shoals, still required its own lighthouse. By this time, the sea around North Ronaldsay had been carefully surveyed, and the site for the new tower at Dennis Head chosen to give maximum warning of the Reef Duke and Seal Skerry.
“The necessity for giving an extensive range to the light at North Ronaldsay, which is to warn the mariner of his approach to the North Foreland of Orkney, combines with the lower level of land, to render a high tower unavoidable”.
In a situation where there are no good materials for masonry and to which every thing must be transported by sea under all the disadvantages of bad anchorage and difficult landing, the elevation of 130ft, which I have found necessary to give to the Tower, must involve a larger outlay than usual. I have, accordingly, introduced brick work as affording greater facility of shipment”.
So Alan Stevenson wrote to his “Report on the Offers for North Ronaldsay Lighthouse January 8, 1852”. In his thorough-going manner, Stevenson had also designed an iron tower, so that the Commissioners might choose the more economical structure, at the same time he voiced the misgiving that in high winds the vibrations of an iron tower might affect the apparatus.
On Stevenson’s recommendation, the Commissioners accepted the lowest offer of £6,181-8-7 for a brick tower from William Kinghorn, a “respectable builder” of Leith.
Kinghorn had first to build a stone jetty of half-a-mile with the help of locals. North Ronaldsay possessed what is still the highest land based lighthouse in the British Isles. Soaring to a height of 139ft, the gleaming red brick tower must have been a source of wonder to the inhabitants of the island. It dominated the low lying crofts, its revolving beam sweeping over the lighting up and the land as well as the sea, to the benefit of night visitors.
In 1889, the red brick tower was painted with two white bands to distinguish it as a day mark.
There have been many changes since a light was first shown. In 1907, the light was change to incandescent. A radio beacon was added in 1932, and in 1971 further improvements were made to this.
North Ronaldsay Lighthouse was automated on 30 March 1998.
