There's an unmarked cemetery in the heart of San Francisco, where hundreds, possibly thousands, of graves rest beneath the popular destinations like the Main Library, the Asian Art Museum, and the United Nations Plaza. Beth takes us through the history of this place, once called Yerba Buena Cemetery, and touches on the history of SF burials before and during the Gold Rush.
