Schackenborg Castle is located in Møgeltønder. The castle's original buildings date back from the 13th century. At the time, the castle was owned by the Bishop of Ribe. In 1661 the castle, then called Møgeltønderhus, was bought by Count Hans Schack. In order to replenish the castle with greater splendour, he initiated several new constructions, including the present main building. The castle was subsequently named Schackenborg and remained family property for eleven generations. One of the owners was the "evil countess", Anne Sophie Schack, who was an energetic collector of estates. In addition to Schackenborg Castle, she also owned Gram Castle, where she is said to haunt the premises even today. The last count, Hans Schack, was childless and died in 1978. He bequeathed Schackenborg as a future residence for Prince Joachim of Denmark. His Royal Highness Prince Joachim owned Schackenborg until 2014.
