The cathedral's treasury has found refuge in the Bischofshof, the old episcopal palace (14 and 16C). Here you will see a collection of religious objects - chalices, monstrances, reliquaries and altar facings from the 11 -18C. Among the most lovely pieces are the Ottokar cross (approx 1430) and the Schaumberg altar (1534-1540) in the Chapel of the Twelve Messengers.
