Loretto and the Miraculous Staircase 1st edition

Who built the mysterious spiral staircase in the little chapel at Loretto Inn in Santa Fe, New Mexico? Was it a master craftsman or the work of good St. Joseph? Archbishop John B. Lamy had the chapel, patterned after the Sainte-Chapelle of Paris, built for the Sisters of Loretto and the young ladies of the academy. When the school closed after more than a century of outstanding service the site was sold. Old and new owners agreed that the chapel, and the famous staircase, must be preserved for its beauty and peace, now and in the future.
