In the Papal Palace in Avignon, expanded between 1335 and 1365 and considered one of the largest and most significant residences of medieval Europe, a distinctive functional program was developed. According to some researchers, this program had a substantial impact on the functional organization of the residence of the Grand Masters of the Teutonic Order in Malbork and the Czech kings at Prague’s Hradčany. The aim of the proposed paper is to critically analyze these hypotheses and to examine whether a similar phenomenon of adapting the Avignon residential model may have occurred in the Royal Castle on Wawel Hill.
