The jetty from the year 1513 on the 4th courtyard boast three oldest coats-of-arms in the Český Krumlov castle. Facing the jetty, the emblem of Lords of Kravaře (wrapped bullet) is located on the left-hand side, in the middle is a typical Rosenberg coat-of-arms, plus the emblem of the Lords of Pernstein (aurochs' head). The Rosenberg coat-of-arms represented Petr IV. von Rosenberg, the Kravaře coat-of-arms was used by his wife Eliška of Kravaře and the Pernstein coat-of-arms belonged to Wilhelm von Pernstein, who was Peter's close friend and former guardian of Eliška of Kravaře. The Kravaře and Pernstein coats-of-arms are also engraved in corbels that support the jetty.
