Excalibur, named for the mythical sword of King Arthur, uses the Arthurian theme in several ways. Its facade is a stylized image of a castle. Until 2007, a wizard-like figure representing Merlin looked out from a high turret and a mechanical dragon lurked in the moat. However, since 2006 most of the medieval themed statues and scenery have been phased out as part of a four-year renovation and modernization project.
