The cathedral cloister consists of two wings (south and west) as well as three and a half cloister wings (east wing only partly) – it dates from the time of the new cathedral building (approx. 1220 to 1250). The vaults have different ages. In the 14th (perhaps already in the 13th) century the Marienkirche was integrated into the cloister. The south wing consisted of the kitchen and refectory (ground floor) as well as the cathedral school (upper floor), the west wing of the economic cellar, chapter house (ground floor) and dormitory (upper floor); the east wing originally housed a syndicate or court house. The gate house was rebuilt in 1940. Remarkable is the special case of a second cloister on the north side of the cathedral church, of which remains are still recognizable.
