#6 Loretto Chapel - Santa Fe, New Mexico

The Loretto Chapel is known for the unusual spiral staircase that covers twenty feet with two revolutions. Located in Santa Fe, New Mexico, the stairs had no central support at first, and was a magical feat of carpentry. Using dowels and wooden pegs, instead of metal nails, no one really knows who built it.
