St. Simons Island Lighthouse Museum

Story

The St. Simons Island Light is a lighthouse on the southern tip of St. Simons Island, Georgia, United States. It guides ships into St. Simons Sound and warns of the many sandbars in the area.Original structureThe original St. Simons Island lighthouse, which was built in 1810, was a 75ft early federal octagonal lighthouse topped by a 10ft oil-burning lamp. During the American Civil War, U.S. military forces employed a Naval blockade of the coast. An invasion by Union troops in 1862 forced Confederate soldiers to abandon the area. The retreating troops destroyed the lighthouse to prevent it from being an aid to the navigation of Union warships.Current structureThe U.S. government constructed a new lighthouse to replace the original, building it to the west of the original's location. It is a 104ft brick structure completed in 1872 and was outfitted with a third-order, biconvex Fresnel lens. The lens is one of 70 such lenses that remain operational in the United States. Sixteen of those are in use on the Great Lakes, of which eight are in Michigan. The rotating lens projects four beams of light, with one strong flash every 60 seconds. A cast iron spiral stairway with 129 steps leads to the galley (or watch/service room). In 1876, the lighthouse was overhauled.
