Rosenborg Slot (Rosenborg Castle)
A fairy-tale castle bang in the middle of Copenhagen, turreted and towered Rosenborg was built as the summer residence for Christian IV, who moved in around 1634. Partly designed by Hans van Steenwinckel, Rosenborg continued to grow over many years. With the engaging Royal Danish Collection, the opulent interior of this ornate red-brick castle brims with royal paintings, fine furniture, and tapestries in rooms decorated in Renaissance and rococo styles. Don’t miss fat little cherubs encrusted on the marble ceiling of room 5; Frederick IV’s ornate ivory-inlaid mandolin in room 10; the strange mirrored floor of his dressing room (room 13a), and the majestic red, black, and white tiled Long Hall on the third floor. Royal Copenhagen fans head to room 23 to see rare Flora Danica porcelain from the original flower-patterned service of 18,000 pieces made in 1790. In the Treasury, the Crown Jewels, encrusted with vast diamonds, sapphires, and garnets and sparkling in semi-darkness. The palace is surrounded with the lawns of Kongens Have (Royal Gardens), the perfect picnic venue on sunny days. The formal gardens were commissioned by Christian IV to surround his summer palace. There is an adventure playground for kids and a puppet theater on the edge of the gardens.
