Boyce Gully built a castle for his daughter, Mary Lou, made of native stone - eighteen rooms, thirteen fireplaces, parapets and many charming nooks and crannies, then furnished it with southwestern antiques.
Boyce Gully died in 1945 before he could send for his family. His “princess” was an adult when she moved into her “castle” and began living her fairy tale, perpetuating her dream. She shared her “home” by giving guided tours of her beloved Mystery Castle until her death in 2010.
Mystery Castle is internationally known and its credits are impressive:
The castle is also listed in the Arizona Historic Register and is a Pride of Phoenix Award winner.
