Grand Turk Historic Lighthouse
The Grand Turk Lighthouse was built in London in 1852 and shipped to Grand Turk, where it was assembled in hopes of saving the salt trade. Standing sixty feet, it was designed by Alexander Gordon, who designed lighthouses throughout the British Empire.
The original lighting apparatus consisted of eight Argand whale lamps with reflectors. These reflectors, built in 1851 by Devill & Co. of London, magnified the light to 450 times its original intensity. Simple clockwork machinery was driven by weight which revolved the chandelier, made by the Chance Brothers of Birmingham, England.
By 1943 the lighting system was changed when the same company, the Chance Brothers, installed a Fresnel lens and kerosene light, which had a visibility of fifteen miles. The lens' prismatic glass lenses were designed to extract every shimmer of light and concentrate them into a powerful beam.
Finally, in 1972 the lamp was electrified and automated, and the burner and clock mechanism were removed. Today,

Reynaud, Director of the French Lighthouse Service, credited Aimé Argand himself with the first proposal for an apparatus using an Argand lamp and a reflector. This combination represented a considerable improvement over current (Submitted on February 18, 2011, by Mike Stroud of Bluffton, South Carolina.)
