3 Best Sights in Copenhagen, Denmark

The four identical rococo buildings occupying this square have housed royals since 1784. It's still the queen's winter residence. The Christian VIII Palace across from the royals' wing houses the Amalienborg Museum, which displays the second part of the Royal Collection (the first is at Rosenborg Castle) and chronicles royal lifestyles between 1863 and 1947. Here you can view the study of King Christian IX (1818–1906) and the drawing room of his wife, Queen Louise. Rooms are packed with royal heirlooms and treasures.

On Amalienborg's harbor side is the garden of Amaliehaven, at the foot of which the queen's ship often docks. In the square's center is a magnificent equestrian statue of King Frederik V by the French sculptor Jacques François Joseph Saly. It reputedly cost as much as all the buildings combined. Every day at noon, the Royal Guard and band march from Rosenborg Castle through the city for the changing of the guard. At noon on April 16, Queen Margrethe's birthday, crowds of Danes gather for a special treat: their monarch stands and waves from her balcony at Amalienborg and the Danes cheer her on with many a "Hurra!" Queen Margrethe has been on the throne since 1972.

The Dutch Renaissance Rosenborg Castle contains ballrooms, halls, and reception chambers, but for all of its grandeur, it has an intimacy that makes you think the king might return at any minute. Thousands of objects are displayed, including beer glasses, gilded clocks, golden swords, family portraits, a pearl-studded saddle, and gem-encrusted tables. The underground treasury contains the crown jewels. The castle's setting is equally welcoming. It's in the middle of King's Garden, amid lawns, park benches, and shady walking paths.

King Christian IV built Rosenborg Castle as a summer residence but loved it so much that he ended up living here until his death. In 1849, when the absolute monarchy was abolished, all the royal castles became state property except for Rosenborg, which is still passed down from monarch to monarch.

At the end of Amaliegade, the beautiful Churchill Park surrounds the spired Anglican church St. Alban's. From here, walk north on the main path to reach the fortification of Kastellet. The peaceful walking paths, grazing sheep, and greenery welcome joggers and lovebirds to this still-operative military structure. Built in the aftermath of the Swedish siege of the city on February 10, 1659, the double moats were among the improvements made to the city's defenses. The citadel served as the city's main fortress into the 18th century. In a grim reversal during World War II, the Germans used it as headquarters during their occupation.
