Tuscon's "Wishing Shrine" is on the National Register of Historic Places and it is highly unusual. It is the only shrine dedicated to the soul of a sinner ("El Tiradito" - the castaway) who was buried in unconsecrated ground. The legends tell of a tragic love triangle in the late 1800's. Today it is visited by people who believe that their wishes will be granted if they pray here. You can see in the lower photo that every tiny crevice in the wall is filled with handwritten notes of prayer.
