3 Best Sights in Centrum, Copenhagen

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.

This pretty harborfront neighborhood, whose name means "new harbor," is perhaps the most photographed location in Copenhagen. It was built 300 years ago to attract traffic and commerce to the city center. Until 1970, the area was a favorite haunt of sailors. Though restaurants, boutiques, and antiques stores now outnumber tattoo parlors, many old buildings have been well preserved and retain the harbor's authentic 18th-century maritime character. You can even see a fleet of old-time sailing ships from the quay. Hans Christian Andersen lived at various times in Nyhavn houses at numbers 18, 20, and 67.

The site of Denmark's main cathedral, the Church of Our Lady, has drawn worshippers since the 13th century, when Bishop Absalon built a chapel here. The previous church, consecrated in 1738, was burned to the ground in 1807 during the Napoleonic Wars. Despite the country's poverty after the defeat, the city built a new place of worship, in the then-modern neoclassical style. Inside you can see sculptor Bertel Thorvaldsen's marble sculptures depicting Christ and the 12 apostles, and Moses and David cast in bronze. The funerals of both Søren Kierkegaard and Hans Christian Andersen were held here.
