A tower in the front of the castle’s defensive circuit, erected on the river or moat, serving as a latrine. Equipped with a fortified sidewalk, connecting it with the castle. The term dansker is bound in literature only with Teutonic castles, although this type of construction is also found in other areas. The etymology of the name is disputed. Some believe that the Polish name “gdanisko” was an attempt to humiliate the good name of Gdańsk town, which repeatedly troubled and rebelled against the Teutonic Order. Another theory is about the influence of the old Prussian language, in which dansk was meant to be “wet, humid”.
