The Mystery Castle in Phoenix, Arizona, stands as an enigmatic and captivating landmark, steeped in a history filled with mystery and intrigue. The story of this extraordinary structure dates back to the 1930s, when it was conceived and built by Boyce Luther Gulley.

Boyce was a gifted and eccentric man who worked as a Seattle shipbuilder before being diagnosed with tuberculosis in the 1920s. Seeking a warm climate to improve his health, Boyce relocated to Phoenix, where he purchased a piece of land in the South Mountains.

Over the next 15 years, Boyce dedicated himself to constructing the Mystery Castle, which he envisioned as a gift for his young daughter, Mary Lou, who had never met her father. The castle’s construction was a labor of love, with Boyce using found and recycled materials, including discarded automobile parts, salvaged bricks, and rocks, to create this extraordinary dwelling.

The architecture of the Mystery Castle reflects Boyce’s unique imagination, featuring winding passageways, secret rooms, and curious designs that earned it the title of a “castle of mystery.” Its incorporation of Native American and Mexican-inspired elements adds to its distinct charm. Boyce also designed the castle to have self-sustaining features, such as water harvesting systems and solar heating, ahead of its time in terms of eco-friendly living.

After completing the castle in the early 1940s, Boyce sent a letter to his daughter, inviting her to join him in Phoenix. Tragically, he passed away before she could make the journey. Today, the Mystery Castle stands as a testament to Boyce Gulley’s boundless creativity, unwavering love for his daughter, and his desire to create something extraordinary out of the desert landscape.
