| | A [[gravity]]-defying spiral staircase at Loretto Chapel, a half-mile from the Capitol in [[Santa Fe]], [[New Mexico]], was built without any supporting supporting, nails, screws, or the use of any power tools. The staircase is held together entirely by wooden pegs, without glue.<ref>[https://www.lorettochapel.com/staircase The Loretto Chapel], Loretto Chapel website</ref> It does two full 360-degree turns to reach a [[choir]] loft 22 feet above. Its builder was an unknown visitor to the Chapel around 1880, who worked without pay and used wood unavailable in the area.
