Below: Loretto Chapel has been the subject of many articles, TV specials, and movies including "Unsolved Mysteries" and the television movie titled "The Staircase." The story is that when the chapel was built in 1873, there was no means to get the choir up to the loft in the back of the church. The sisters prayed for an answer and a man appeared at the chapel with a donkey and a toolbox looking for work. Months later, the elegant circular staircase was completed, and the carpenter disappeared without pay or thanks. The rest of the mystery is about the contrucution of the staircase. It has two 360 degree turns and no visible means of support. Also, it is said that the staircase was built without nails—only wooden pegs. Questions also surround the number of stair risers relative to the height of the choir loft and about the types of wood and other materials used in the stairway's construction.
