It's San Francisco County Jail! What a cool looking place for criminals.
What do Alcatraz and San Quentin State Prison have in common?
They are prisons with good views of the SF Bay. Alcatraz is situated in the middle of the San Francisco Bay. Inmates could see the vibrant of SF but could not reach it. Nowadays Alcatraz is one of the major SF tourist attraction while San Quentin remains a prison.
