The Point Robinson Light is an operational aid to navigation and historic lighthouse on Puget Sound, located at Point Robinson, the easternmost point of Maury Island, King County, in the U.S. state of Washington. The site was listed on the National Register of Historic Places in 2004.HistoryDevelopment of a navigational aid at Point Robinson began in 1884, when the Lighthouse Service purchased 24 acres there for $1,000. Construction of a fog signal station began that year with the facility seeing dedication on July 1, 1885. The original boiler and 12-inch steam whistle came from Oregon's Point Adams Light. A one-and-a-half-story keeper's house was built nearby. A second keeper's quarters was constructed in 1907.The point's first light arrived in 1887, when a lens lantern, shining persistent red, was attached to a 25ft post. In 1894, the post was replaced by an open wooden tower which held the light at 31ft. The current lighthouse was built in 1915, a twin of the Alki Point Lighthouse. With its 38ft tower and fifth-order Fresnel lens, the light could be seen 12mi. The flashing pattern is on for three seconds, off for one second, on for another three seconds, and off for five seconds. The light was automated in 1978, using the original fifth-order Fresnel lens. In 2008, the Coast Guard replaced the original Fresnel light with a replaceable plastic beacon mounted outside the lantern room. The original Fresnel lens remains in the lantern room where it can be viewed by visitors.
