Description
Development 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.[3] 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.[6] A second keeper's quarters was constructed in 1907.[3]
The point's first light arrived in 1887, when a lens lantern, shining persistent red, was attached to a 25-foot (7.6 m) post. In 1894, the post was replaced by an open wooden tower which held the light at 31 feet (9.4 m).[3] The current lighthouse was built in 1915, a twin of the Alki Point Lighthouse. With its 38-foot (12 m) tower and fifth-order Fresnel lens, the light could be seen 10 nautical miles; 19 kilometres (12 mi). The flashing pattern is on for three seconds, off for one second, on for another three seconds, and off for five seconds.[7] 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.[6]
