Mare Island Light


Mare Island Lighthouse was a lighthouse in California, United States, on the north shore of San Pablo Bay at the entrance to Carquinez Strait, California.

History

Mare Island Light was built in 1873, deactivated in 1917, and demolished in the 1930s. The lighthouse was designed by Paul J. Pelz, who also designed Mare Island's sister stations, Point Fermin Light in San Pedro CA, East Brother Island Light in Richmond, California, Point Hueneme Light in California, Hereford Inlet Light in North Wildwood, New Jersey, and Point Adams Light in Washington State, all in essentially the same style.
The United States Lighthouse Board later realized that a light positioned offshore near the junction of the strait and river would better serve navigation in the area. The Carquinez Strait Light opened in 1909 to replace this light in purpose, but in an offshore location, between the two channels.
A Navy Direction Finding Station was later erected on the site in 1942. It was manned by U.S. Navy radiomen stationed at Naval Radio Station, Mare Island. The station was closed in 1945 after World War II ended and a Navy Radio Beacon was installed.
