A walk around the actual palace is worth visitors' time. The palace garden terraces offer the best view of the mighty fortifications. To this day, defensive towers bear witness to fateful sieges and successful defenses. The pointed roofs of the casemates can be seen deep down in the castle moat. In the 17th century, the fortifications were partially repurposed: the north casemate, for example, served as a pedestal for the English Building.
