Copenhagen: Rosenborg Castle

Copenhagen has lots of idyllic parks. Its most royal is the King's Garden surrounding the Rosenborg Castle, summer residence to Denmark's "big personality" king, Christian IV, who ruled from 1588 until 1648. The castle's basement holds cases of treasures to dazzle visitors, including the finest renaissance crown in Europe, from Christian IV's coronation in 1596.
