Kronborg Castle, Helsingør -
Immortalized as Elsinore in William Shakespeare's play 'Hamlet,' Kronborg Slot (Kronborg Castle) dates back to the mid-15th century. In 1964, a television play, 'Hamlet at Elsinore,' was filmed in the castle—the only version (with sound) of 'Hamlet' to have actually been shot within its walls. It stars Christopher Plummer in the title role and features Robert Shaw as Claudius, Donald Sutherland as Fortinbras, and Michael Caine as Horatio. The castle is a cherished UNESCO World Heritage Site.
