Remembering how he built sand castles with his daughter in his native Seattle, Boyce Gully "disappeared" to Phoenix and built a native stone castle with 18 rooms, 13 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 daughter, Mary Lou Gully, 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.
