Small Kitchen Parts of the 16th-century royal kitchens are preserved in this chamber: foundations of the pillars that supported stove hoods, remnants of ovens, and the original ceramic tile floor. Late medieval ceramics, such as kitchen vessels, tableware, floor and stove tiles, are displayed in glass cases. Also on view are models of the 15th-century psalm singers house founded by Jan Długosz and the 14th-century Gothic cathedral.
