Mystery Castle is the embodiment of eclectic. The original owner built the "castle" out of anything he could get his hands on, whether it was discarded bricks to empty liquor bottles. It's really amazing to see the result of years of hard work and the knowledge that 2 years of architectural building school will achieve with just a little imagination. Mystery Castle is the type of place you would have loved to run around and play hide and seek as a kid. There are so many unique details that make the house itself a work of art. Tours are held quite frequently, and you can jump in at any part of the tour and go to another one once your part of the tour is over. Admission to tour the castle is $10. Definitely a great place to take visitors for some quirky old school Arizona history!
