Loretto Chapel is a historic chapel located in Santa Fe, New Mexico. Built in 1878, it is known for its stunning Gothic architecture and beautiful stained glass windows. The chapel was originally part of a girls' school run by the Sisters of Loretto and is now a popular tourist destination. One of the chapel's most famous features is its spiral staircase, often referred to as the "Miraculous Staircase." This unique wooden staircase has two complete 360-degree turns and no visible means of support. Its construction remains a mystery, adding to the chapel's allure and charm.
