An outstanding feature of the Chapel is the stained glass. The four windows in the vestibule relate to the apparition of the Blessed Virgin at Banneux in Belgium in 1933, when she stated “I am the Virgin of the Poor.” This is one of the sources of inspiration on which the work of the former Dominican Sisters of the Sick Poor was based.

Several elements in the chapel at Mariandale that appear to be abstract are, in fact, representations of Church teachings. The reredos, the ornamental partition wall behind the altar, is adorned with modern, hammered-brass arms. These represent the seven gifts of the Holy Spirit: wisdom, understanding, counsel, fortitude, knowledge, piety, and fear of the Lord.

The windows at either side of the white marble holy water font depict the sacrament of baptism, which brings us into the faith community, and the sacrament of penance, which reconciles us with God and with one another.

The stained glass windows on either side of the main seating area depict “The Creed” in abstract form, bringing the glory of the colors into the chapel itself to create a joyous atmosphere for the celebration of the liturgy.

On either side of the main chapel seating area are ten (1–10) windows that depict the Creed. Start at the rear of the seating area on the left side (facing the altar) and proceed toward the altar. Continue on the other (right) side of the chapel near the altar and proceed toward the back of the seating area.  These windows read as follows.

1. Window 1:  I Believe in One God the Father Almighty
2. Window 2:  Maker of Heaven and Earth
3. Window 3:  And I Believe in One Lord Jesus Christ the Only Begotten Son of God
4. Window 4:  And He Became Flesh by the Holy Spirit of the Virgin Mary and Made Man
5. Window 5:  He Was Also Crucified for Us
6. Window 6:  Suffered Under Pontius Pilate
7. Window 7:  And Was Buried
8. Window 8:  He Rose Again
9. Window 9:  He Ascended into Heaven
10. Window 10: I Believe in One Holy Catholic and Apostolic Church…I Await the Resurrection of the Body

At either side of the altar are windows carrying themes of the Eucharist (11) – the wheat of the bread, and the grapes (12).
