Holger Danske

In the catacombs under Kronborg Castle, you find one of the major Danish heroes - Holger Danske, or Ogier the Dane. The legend has it that he never lost a battle in his life. However, he got increasingly homesick, and finally decided to walk from the South of France and Emperor Charles' court, back to Denmark - which he did.
Upon arrival at Kronborg he sat down and immediately fell asleep, and still sleeps today. According to the legend, if Denmark at some point in time should have its sovereignty threatened, Holger will once more awake and do battle for Denmark!
