It is located near the southernmost point of mainland Alaska. HistoryThe Lighthouse Board approved the construction of the Tree Point Lighthouse on April 24, 1903, and just over a year later the light was activated on April 30, 1904. The lighthouse was the first, and only lighthouse, to be built on mainland Alaska. In the early 1930s, the Bureau of Lighthouses authorized reconstruction of the station with reinforced concrete. Work began in 1933 and was completed in 1935. The 1935 lighthouse was equipped with a fourth-order Fresnel lens, which is now displayed at the Tongass Historical Museum in Ketchikan, Alaska. In 1969 it was automated. The Fresnel lens was replaced with a lens mounted outside the lantern room. In the summer of 1977 the lens on the gallery was replaced with a modern, solar-powered VRB-25 Vega lens placed back inside the lantern room. The lighthouse was listed on the National Register of Historic Places as an historic district in 2004.[3] Its 2003 NRHP nomination stated that it was "the most intact [lighthouse] outpost in the southern section of Southeast Alaska. The listing includes the concrete light and fog-signal building built in 1935, one standing keeper residence, the two original oil houses, the later-period boathouse, and features of the water supply system. In addition, the tramway run is relatively intact." Additional features of a derrick and winch were deemed non-contributing, because they are relatively recent replacements.[4] See also{{stack|{{Portal|Alaska|Lighthouses}}}}
