The altarpiece has a total of 24 framed panels. They make up two views, open and closed. The upper row of the opened view shows Christ the King between the Virgin Mary and John the Baptist. The insides of the wings show angels singing and making music. On the outside is Adam and Eve. The lower row of the central panel shows the adoration of the Lamb of God. Several groups are in attendance and streaming in to worship, overseen by the dove who is the Holy Spirit. On weekdays the wings were closed. This showed the Annunciation of Mary and donor portraits of Joost Vijdt and his wife Lysbette Borluut.
