History

An 1910 screw-pile lighthouse — also called the Vallejo Light — at the narrow passage connecting San Francisco Bay to the Sacramento–San Joaquin Delta. Decommissioned and demolished. An automated light now marks the strait.

Why it matters

Closes the loop on the small cluster of inland-bay screw-pile lights that supported Bay-to-Delta navigation in the late 19th and early 20th centuries — Mare Island, Southampton Shoal, Roe Island, and Carquinez Strait.

The visit

No remnant of the original lighthouse exists at the site. No public access; documentation lives in archives and old photographs.

Worth knowing about as part of the Navy's California history more than as a lighthouse destination. The structure's current condition and ownership remain under-documented — a real research gap on this site, not a story we're skipping.
