The Crown Bakery, located on the southern side of the perimeter wall, is one of the oldest surviving buildings in the castle area. The medieval perimeter wall served as its southern outer wall. The bakery was built as a two-story structure: the ground floor housed six baking ovens, and the upper floor had a barrel-vaulted drying loft. Construction began in 1740 and was completed in 1747. Even when finished, the bakery was oversized for the army's needs. With a single firing, the ovens could bake nearly 700 kg of bread and 400 kg of hardtack.

During the prison era, the upper floor of the Crown Bakery was used as the prison hospital, while the lower floor became kitchen space. The original ovens were gradually dismantled but were rebuilt during the castle’s restoration in the 1970s using old plans.

In the summer, the Crown Bakery hosts a café, and the space is frequently rented for private events and celebrations, such as weddings, graduations, and dinners.
