RPPC: Holy City, Calif.

Holy City is an unincorporated community in Santa Clara County, California. Once considered a Utopian community in the 1920s and 1930s, it is now considered a ghost town. The town is located in the Santa Cruz Mountains.
Holy City was founded in 1919 by cult-leader William E. Riker and about thirty of his followers. Calling his ideology "The Perfect Christian Divine Way", Riker preached celibacy, temperance, white supremacy, and segregation of the races and sexes.
