Overview
Mystery Castle is an extraordinary 18-room structure tucked into the foothills of South Mountain Park in Phoenix. Conceived and built by Boyce Luther Gulley between the 1930s and 1945 using an eclectic mix of stone, adobe, railroad ties, auto parts, telephone poles, glass bottles, and recycled materials, it stands as a whimsical testament to creative resilience. Ideal for tourists, local families, art enthusiasts, and history buffs, the Castle offers guided tours through its chapel, dungeon, cantina, and living spaces—each brimming with folk-art charm, quirky details, and a surreal sense of discovery . Though tucked away in desert surroundings, its imaginative architecture, homemade mosaics, trapdoors, and petroglyphs create an enchanting experience that transcends typical historical sites.

History
The story of Mystery Castle begins in the late 1920s, when Boyce Gulley, diagnosed with tuberculosis, relocated from Seattle to Phoenix to help his health in the drier air. Inspired by shared memories of building sandcastles with his daughter Mary Lou, Gulley began constructing a permanent castle using discarded and natural materials strewn across the South Mountain area. Over the next fifteen years, he hand-built eighteen rooms, thirteen fireplaces, a chapel, a cantina, dungeon, and whimsical living areas—all without formal plans or permits. After his death in 1945, Mary Lou and her mother moved in and soon began offering tours, gaining national recognition through a 1948 Life magazine feature. Mary Lou continued stewardship until her passing in 2010, after which the Mystery Castle Foundation took over. In 2025, the Castle was listed as one of the National Trust’s 11 Most Endangered Historic Places, highlighting both its cultural value and preservation needs.

Points of Interest
The Chapel and Shoe Tradition
The quaint chapel is one of the Castle’s most charming interiors: a hand-built sanctuary featuring quirky folk-art touches and a display of single shoes left by brides, symbolizing a whimsical local superstition . Inside this sacred space, guests can sense both personal devotion and playful creativity—Mary Lou encouraged brides to leave a shoe for luck, creating an evolving folk-art installation. The blend of handmade mosaics, intimate craftsmanship, and heartfelt story-telling makes the chapel a memorable highlight for visitors and couples alike.
Saguaro Room & Indoor Garden
One of the most enchanting rooms is built around the skeleton of a saguaro cactus—the focal point of what was once a living centerpiece. This cactus-themed room features natural ventilation and cool air channels through glass-block windows, anchored by stone mosaics and colorful trinkets. It offers a peaceful oasis within the rugged Castle, giving visitors a moment of reflection and delight. It also showcases Gulley’s ingenuity in integrating desert flora into structural design, marrying nature with architecture.
Dungeon and Secret Passages
The Castle hides a playful “dungeon” space beneath trapdoors and winding corridors—evoking a childlike sense of adventure. Built by a father building a dream for his daughter, this area is a quirky twist on classic castle lore, complete with unexpected nooks and storage areas filled with found objects and folklore. Visitors especially enjoy exploring hidden rooms and discovering small treasures—every nook encourages curiosity and delight.
Folk-Art Interiors
Throughout the Castle’s interiors—living room, guest suites, kitchen—visitors encounter folk-art installed by Gulley and Mary Lou: from plumbing fixtures to petroglyph motifs, car rims as windows, bottle mosaics, and donkey saddle seats. Each surface tells a story: recycled telegraph poles, slate chalkboards in floors, stained glass fridge-box windows—every artifact reveals resourceful creativity. Guests marvel at this mash-up of materials and themes, making a simple tour feel like a treasure hunt through an artist’s workshop and personal fairy tale.
