Nestled in the foothills of South Mountain Park in South Phoenix, Mystery Castle stands as a testament to a father’s love and ingenuity. Built by Boyce Luther Gulley in the 1930s after he moved to the area to treat his tuberculosis, the castle was a gift for his daughter, Mary Lou. This unique structure, now a Phoenix Point of Pride, is one of 33 attractions that showcase the best of the city. Visitors can explore the castle’s eclectic design, which features a mix of materials and architectural styles, offering a glimpse into the creative vision of its builder.
