Copenhagen's Nyhaven, or "New Harbor," is actually steeped in a long heritage. Colorful buildings line the canal and hint at a history of small-vessel traffic. Like many ports, this strip has a salty history, rich with sailors, drinking and literary exploits. Danish author Hans Christian Andersen made his home in Nyhavn as well. It's cleaned up now and is a lovely place for a stroll.

Born of a fairy tale by Danish author Hans Christian Andersen, the statue incarnation of the Little Mermaid has watched over Copenhagen's harbor since 1913. In 2010, Den Lille Havfrue, as she is known in Danish, left her post to represent Denmark at the World's Fair in Shanghai.

The beautiful 400-year-old castle is situated in central Copenhagen's popular park, The King's Garden. The castle was built by one of the most famous Scandinavian kings, Christian IV. Today, the glory of the past can be experienced through the numerous art treasures of the previous kings and queens. Among the main attractions is the Great Hall with the coronation thrones and three life-size silver lions standing guard. The crown jewels and royal regalia sparkle behind the thick walls of the treasury beneath the castle.

The Round Tower Lookout Tower – Observatory – Exhibitions – Concerts.One of the best-known and most popular structures in Denmark, the Round Tower has been a distinctive feature of the Copenhagen skyline since 1642. The Tower once soared far above the rest of the rooftops in the city, and University astronomers studied the stars and planets from the Observatory at the top. The scholars may have forsaken the building a long time ago, but during the winter visitors are still able to gaze at the cosmos from Europe's oldest functioning observatory. The platform that runs around the outside of the Observatory affords views over the old Latin Quarter – from here, you can spot most of the city's famous buildings. The Round Tower does not have an elevator, so visitors have to climb the winding, white-washed Spiral Walk, where kids often hide in the niches, only to jump out shouting “boo!” as adults approach. Halfway up the tower is the entrance to the large and stunningly beautiful Library Hall, which now serves as a popular gallery and concert venue. It hosts several exhibitions a year, and stages concerts almost every week. Above the Library is the Bell Loft, notable for its enormous wooden beams, which were used in the reconstruction of the Tower following the great fire of Copenhagen in 1728. The Loft is also home to a small exhibition of fascinating artefacts from the Tower's history, including Christian IV's wax seal, a tin of medicine produced by Tycho Brahe, and a piece of the bomb that exploded in the Library Hall during the bombardment of Copenhagen in 1807.The Round Tower was built by Christian IV between 1637 and 1642. It was the first part of the Trinitatis Complex, which combined church, library and observatory in a single building.

Opening hours of the tower: Every day, 09:00 - 20:00 from February 1st until December 31st. Opening hours of the church: Every day, 11:00 - 15:30. Please note that the church is closed for sightseeing during services and other activities taking place in the church.

Christiansborg Palace is situated on the little island of Slotsholmen (Castle Island) which is surrounded by canals in the heart of Denmark's capital, Copenhagen. Denmark has one of the oldest monarchies in the world, and the palace has a long, dramatic history which revolves around the exercise of royal power. Today, Denmark is a constitutional monarchy with a parliamentary system of governance. Under its beautiful copper roof, the palace houses the Danish parliament, the office of the Danish prime minister and the Supreme Court. It is therefore the center for legislative, executive and judicial power in Denmark. The palace also accommodates rooms for the Danish Monarchy. Focusing on the royal part of the palace, Christiansborg Palace is H.M. the Queen's working palace. This is where the Queen holds audiences, signs laws, holds banquets and receptions, celebrates royal anniversaries and receives state visits. It is a working palace where old traditions and the modern Royal Family meet. You will see dazzling halls, adorned with colorful tapestries, vast paintings, patterned floors, glittering chandeliers, and sumptuous stucco ceilings. You can explore The Royal Kitchen and see its two tons of shiny copper kitchenware. You can visit the beautiful palace chapel, stand underneath its dome and let your head spin as you gaze up at the angels in the ceiling décor more than 30 metres above you.
