Point Blunt Light

Point Blunt Light stands on the southeast corner of Angel Island and features a concrete signal building positioned to guide ships through San Francisco Bay. The structure sits at an elevation of 60 feet, allowing its light to be visible across the water for maritime navigation.

The lighthouse began operations in 1915 to improve navigation in San Francisco Bay during a period of expanding maritime infrastructure development. It later became the final manned navigation station built in California before the shift toward automated systems.

The lighthouse represents the final manned navigation station constructed in California, reflecting the transformation of coastal maritime operations in the region.

The light flashes every five seconds to guide vessels through the bay, and the station has been fully automated since 1976. The site sits on an island, so visitor access is restricted, though the structure is visible from outside Angel Island.

The station included four separate residential units with three bedrooms each, built to house Coast Guard personnel who operated direction finder calibration services. This setup reflects how critical the location was for supporting advanced navigation technologies beyond basic lighthouse operations.
