S.S. Palo Alto

It's a decaying concrete tanker built during the first World War. She wasn't finished before the war ended so instead she was put into early retirement. In 1929, she was moved from her original location in Oakland to her current position, then used as for amusements such as dancing and swimming. That lasted for two years in the Depression era, but thereafter she became a fishing pier until the ocean waters caused enough erosion to make her unfit for recreation. In 2017, a violent storm broke her in half. Now, she serves as an artificial reef for marine life. While you can view the ship from the beach, it is closed to the public.
