Four alcoves in the rectangular alcove towers had defensive and residential functions. The alcoves in the corners of the Great Chamber retain the look similar to their original one. Wall paintings, Renaissance toilets and fireplaces have been preserved in both of them. Numerous windows in the alcoves made it possible to observe the surrounding areas that were incessantly under the threat of robberies and raids. A round opening made it possible to use of a primitive firearm called an arquebus. Renaissance toilets (Lat. ‘locum secretum’) were wall recesses with a seating board where the waste flowed down through an opening and into barrels. Alcove walls on the left side of the room are covered by polychrome from the mid-18th century. The interior houses another part of the Meaning of the Renaissance exhibition, i.e., the Kunstkammer or a cabinet of curiosities that shows what people were interested in during the Renaissance. For example, you can see minerals with ‘magical’ properties, fossils, prepared exotic animals, the largest butterfly species and reprints of old maps in the display cabinets and on the walls. A cut-out fragment of the floor reveals a view of the winding staircase leading from the Journeyman's chamber to the first floor.
