The study deals with the bohemian estates in the Upper Palatinate (northern Bavaria), which was incorporated by the emperor Charles IV in 1355 to the Czech Crown. A special attention is paid to the Lauf Castle (to the East of Nürmberg) built by Charles IV.
There is a hall decorated with coat of arms (112 pieces) of the Czech Crown, clerical institutions and mainly bohemian nobility. There is a relief of S.
Wenceslaus in the hall and in the entrance tower, as well. Certainly, the Lauf Castle rapresented the power of the king of Bohemia.
