What started as a two-room cathedral in 1858 has grown into the beautiful church we see today in downtown Tucson at 192 S. Stone Ave. In a 2014 interview with the Arizona Daily Star, ghost tour guide Robert Owens said the church was one of his favorite places to visit because it's been said to be the home of a faceless nun who levitates in the courtyard.

“The faceless-nun phenomenon has actually been reported all over the world at really old churches and haunted locations that have a religious history aspect to it,” Owens said. “So it’s kind of a strange archetypal myth, if you will.”
