The windows in the Lady Chapel honor the special privileges that initiated and climaxed Mary's life on earth. The one on the left side of the chapel is dedicated to the Immaculate Conception: Mary was conceived without the stain of Original Sin, by a special grace from the Father, so that she could carry the holy presence of God within her womb. Click each picture in the window to find out what they depict. Then click here to see the separate, Salve Regina window.
