Mystery Castle

Mystery Castle is located in the city of Phoenix, Arizona, in the foothills of South Mountain Park. It was built in the 1930s by Boyce Luther Gulley for his daughter Mary Lou Gulley. After learning he had tuberculosis, Gulley moved from Seattle to the Phoenix area and began building the house from found or inexpensive materials. Boyce Gulley died in 1945, and Mary Lou and her mother were notified by attorney that they had inherited the property. Shortly after, the mother and daughter moved in.

Their story attracted attention, giving the home some renown as well as its exotic name: A Life Magazine story used the headline "Life Visits a Mystery Castle: A Young Girl Rules Over the Strange Secrets of a Fairy Tale Dream House in the Arizona Desert." The photograph featured Mary Lou posing atop the cantilever staircase leading to the roof of the house. That same year, Mary Lou and her mother began offering tours of the home.
