The Marienaltar (Altar of the Virgin) is the oldest of the altars in the Wolfgangskirche with the main statue of the Virgin with Child dating from around 1480-90, while the statue of St Wolfgang on top is from around 1470.
The wings are by Wilhelm Ziegler — his WZ and 1515 appear on both wings that illustrate scenes from the lives of Holy Roman Emperor Heinrich II (Henry II), who was declared a saint, and St Nicolaus.
