In the east choir there is also the main altar of the church. There is one of the few altarpieces preserved in the cathedral: a carved altar from around 1510. It is dedicated to the Virgin Mary. The artist is unknown, but a Thuringian workshop is suspected. In the middle, Mary appears with the Child Jesus. On the left is Saint Catherine and on the right, with the chalice in her hand, Saint Barbara. And in the side wings you can see the twelve apostles.
