Mystery Castle - Boyce Gulley's eccentric build

Mystery Castle in Phoenix was constructed in the 1930s by Boyce Luther Gulley using found and salvaged materials; Gulley called it a gift for his daughter Mary Lou. The 18-room structure and its origin story are prominent pieces of local lore and the site is operated as a small museum. Elements of Gulley's personal narrative and some construction details have been debated by historians, making the tale part documented history and part local legend.
