MYSTERY CASTLE
Mystery Castle is located in the city of Phoenix, Arizona, in the
foothills of South Mountain Park. It was built in the 1930s by
Boyce Luther Gulley for his daughter Mary Lou Gulley.
After learning he had tuberculosis, Gulley moved from
Seattle to the Phoenix area and began building the house
from materials found in the desert. Boyce Gulley died in 1945,
and Mary Lou and her mother were notified by attorney
that they had inherited the property. Shortly after, the mother
and daughter moved in.
Said to be held together by a combination of mortar, cement, calcium, and goat milk, the
sprawling 18-room, three story castle is built from a wide range of materials — stone,
adobe, automobile parts, salvaged rail tracks from a mine, telephone poles, etc. It features
a chapel, cantina, and a dungeon. Parts of the castle remain unfinished, and electricity
and plumbing weren't added until 1992. As the housing boom progressed in Phoenix, new
development encroached close to the castle and its grounds, making it far less isolated.
