“The Barbican - an element of medieval fortifications; a circular defensive structure with loop-holes, in front of the town walls. In Europe this kind of building has been preserved only at Carcassonne (southern France), Zgorzelec (Görlitz), and of course in Cracow. (...) It was at that time, that one of the largest European buildings of this kind came to to exist in Cracow, being nowadays the best preserved example of the medieval barbican.”
