Engraving showing the design for the Bell Rock Lighthouse by John Rennie (1761-1821), supervising engineer of the project. The Bell Rock, 10 miles off the coast of Scotland, is submerged by the tide twice a day and many ships were wrecked, claiming hundreds of seamen's lives, until a lighthouse was built. The Bell Rock Lighthouse, built to Robert Stevenson's (1772-1850) design, has lasted into the 21st century. Illustration from Stevenson's 'An account of the Bell Rock Light-house: including the details of the erection and peculiar structure of that edifice; to which is prefixed a historical view of the institution and progress of the Northern Light-houses', published in Edinburgh in 1824.
