It’s not surprising to learn that the St. Ignatius Mission, located on Montana’s Flathead Indian Reservation, is included in the U.S. National Register of Historic Places. Or unusual that the reason for its listing is the 58 stunning murals that adorn the mission’s walls and ceiling. What is uncommon, though, is Brother Joseph Carignano: the untrained amateur artist employed at the mission as a handyman and cook who painted them all in his spare time.
