Imposing wrought iron gates welcome visitors and worshippers into the quiet reverence of St. Mary’s Chapel, just to the left of the high altar.
The intricately carved and gilded reredos is carved of linden wood and depicts key moments in Mary’s life, including the Annunciation, the Wedding at Cana and Pentecost. Following medieval custom, the benefactors of the chapel, Larz and Isabel Anderson, are represented by two tiny kneeling figures in the bottom corners of the reredos.
The Andersons, who are interred in St. Mary’s Chapel, also donated six 16th-century Flemish tapestries that were woven in Milan. The tapestries depict scenes from the life of David, including his victorious encounter with Goliath.
Above the tapestries, the stained glass windows depict the parables of Jesus, and the boss stones at the center of the ceiling depict the seven sacraments of the Church: baptism, confirmation, matrimony, holy orders, penance, anointing of the sick, and Holy Communion.
