The Loretto Chapel in Santa Fé, New Mexico, attracts around 250,000 visitors annually due to its 'miraculous' staircase, constructed in the 19th century without nails or glue. A carpenter, who appeared after nuns prayed for help, built the staircase without any central support and vanished after completing it, leading to speculation that he was St. Joseph. The staircase's mysteries include the unknown identity of the carpenter, the engineering impossibility of its design, and the origin of the unusual wood used, which does not exist in the region.
