A significant element within the chapel is the Schnewlin altarpiece (ca. 1514/15). Based on a design by Hans Baldung Grien, the group of sculptures depicts the Holy Family on the Flight into Egypt (realised by Hans Wydyz) in front of a painted landscape by Hans Leu the Younger. The left wing of the altarpiece shows the Baptism of Christ by John the Baptist and the right wing the Vision of St John the Apostle on Patmos. While initially intended to be positioned in front of the left wall so as to be gazing at the beholders in the ambulatory, currently the figures are placed on the right facing the wall.
