The English Tower. The three-storied tower was constructed between 1399-1413 AD. There are two doors, one opening to the north to the inside of the castle, the other opening onto the western rampart. Access to the tower was through a draw-bridge. On the western façade the carving of a lion, dating from antiquity, can be seen. For this reason the tower was known as the Lion Tower. Above the lion are the royal arms of Henry IV of England (1399-1413). The same arms are carved over the entrance to the lower entrance to the interior of the castle. On the top of these arms there is a roaring lion standing of a helmet of power. On either side are arms of nobles who supported the construction.
