Just off San Pablo Point, near the Richmond-San Rafael Bridge, there's a tiny spec of an island with a beautiful Victorian-era building on it. East Brother Light Station has been there since 1874, its light beaming out to warn boats away from unexpectedly shallow waters. Bay Curious listener Kathleen Taylor noticed the lighthouse on a ferry ride from Vallejo to San Francisco for a baseball game and wondered what went on there over the years. She tagged along as we visited the island and got a private tour with the current keepers.Additional Resources: A Trip to the Remote Island Lighthouse in the Middle of San Francisco Bay Read the transcript for this episode GoFundMe for East Brother pier replacement Sign up for our newsletter Got a question you want answered?
