Rosenberg Castle, Denmark- Christian IV's resident Castle. The throne, left, was made, it was said, of unicorn horn (narwhal tusk) in 1665. The silver throne of the Danish queens was made in 1730. Three life-size silver lions from the 1660's guard the double thrones on a two-step dias, each throne with a canopy. Denmark no longer has coronations and the thrones have not been used since 1840, but the lions are still used at the royal "cast rum deloris" accompanying the catafalque or bier.
