Alki Point Lighthouse, 2007

The Alki Point Light is located at Alki Point, at the southern entrance to Seattle's Elliott Bay. In 1887, the United States Lighthouse Board finally recognized the need for an official light and placed a lens-lantern atop a wooden post at the point.

Several years later, the Lighthouse Service decided to upgrade the light and add a fog signal at the point. The present concrete fog signal building with the 37-foot octagonal tower was completed in 1913.

The fourth-order Fresnel lens was eventually replaced by a modern optic during the 1960s. Alki Point remains in service today. It is listed as Alki Point Light, number 16915 in the USCG light lists.
