Southampton Shoal is a former lighthouse site in California, United States. A platform sits at the southwest edge of Southampton Shoals, northeast of Angel Island in the San Francisco Bay. The platform is all that remains of the original structure and supports an automated bell which chimes every ten seconds and red light mounted on a pole, which flashes on for three seconds and is then dark for 3 seconds in each six second cycle (Iso R 6s).[1]

History

Southampton Shoal Lighthouse was a square building built on a platform supported by wooden piers. It was built and first lit in 1905 with a fifth order Fresnel lens. The original lens is on display at the Angel Island Interpretive Center.

In 1960, the structure was moved to Tinsley Island 38°02′10″N 121°29′39″W / 38.035986°N 121.494152°W / 38.035986; -121.494152 which is a private island in the San Joaquin River delta close to Stockton. The island is owned by the St. Francis Yacht Club of San Francisco. The building is now in use for lodging.
