SAR036706 SCOTLAND (1959). Kinnairds Head Lighthouse Fraserburgh, Aberdeenshire, Scotland. An oblique aerial photograph taken facing South/West.

Kinnaird Head Lighthouse. This was the first of many lighthouses to be constructed by Thomas Smith, followed by his stepson Robert Stevenson and Robert's sons, David, Alan and Thomas; grandsons, Charles Alexander and David Alan; and great grandson David Alan. 'The original light at Kinnaird Head Lighthouse was established by Thomas Smith on 1 December 1787. A lantern was set 120 feet (37 m) above the sea on a tower of the old castle. Whale oil lamps produced a fixed light, each backed by a parabolic reflector. Kinnaird Head was the most powerful light of its time, and contained 17 reflectors arranged in 3 horizontal tiers. It was reported to be visible from 12 to 14 miles (10 to 12 nmi; 19 to 23 km). The first lighthouse keeper was James Park, who was paid a shilling per night and remained in the job for nearly a decade.' - Wikipedia, see https://en.wikipedia.org/wiki/Kinnaird_Head_Lighthouses See also https://en.wikipedia.org/wiki/Thomas_Smith_(engineer)
