For the first five years that the retreat center was, very little was was known about the beautiful stained-glass windows of the chapel. In 2022, Chaplain Fr. David Huemmer wrote to the archivist of the Congregation of St. Joseph who shared the original 28-page Iconography of the Stained-Glass Windows booklet.
The typewritten (with handwritten notes!) document has been updated using computer word processing. St. Maria Goretti parishioner Sara Musick photographed new images of all the stained glass as well.
The updated Iconography is linked to the website and available in the lectern bookshelf just outside of the Chapel.
