Many of Denmark’s royal castles are still residences used by the Danish Royal Family:

Amalienborg

Her Majesty Queen Margrethe II’s winter residence, is situated in the middle of Copenhagen with its four, almost identical Rococo palaces surrounding the monumental castle courtyard. Two of the palaces are partially open to the public.

Fredensborg Palace

Is situated in North Zealand where the royal family resides during the summer. The palace itself is usually open during the month of July. Other royal castles today serve other purposes – housing public institutions, the Danish government and parliament, museums, etc.
Find more information about the royal castles on the official website of the Danish Monarchy www.kongehuset.dk/english/  

The Palaces and Properties Agency preserves and develops most of Denmark's well-known castles and gardens, including Kronborg Castle, Amalienborg, Christiansborg Palace, Koldinghus Castle and Rosenborg Castle Gardens ("the King's Gardens").
 
A guide to royal palaces and castles

In addition to Denmark’s royal castles, the many castles and manor houses of the nobility lie like gems in the most scenic of settings. Here every style of architectural history is represented, from the severity of the medieval fort, through Renaissance, Baroque, Rococo and French to a merry mixture of them all. These impressive residences recount the story of Denmark’s history, its culture, its architecture and not least its family histories, since in many cases the estates have been in the same family for centuries.

Artists’ retreats

For centuries the Danish castles stood as residences and power bases for the royal houses, nobility and a narrow élite. At the same time, they provided sanctuaries for great Danish artists, who were invited to take up residence and given a gracious setting for their work. The writer Hans Christian Andersen and the composer Carl Nielsen were frequent guests at Danish castles and manor houses.

The castles were often bastions of royal power, strategically positioned for defence against enemies. Enemies came from the south, where the impressive fortress of Koldinghus stands close to the old border with Germany, or from the east, where Kronborg Castle in Helsingør (Elsinore) guards the mouth of the Sound. Today Kronborg is inscribed on the UNESCO World Heritage List.

In earlier times the wrought-iron gates were locked and the great oak doors were thereby closed to the public, but today more than 50 castles and manor houses have opened their doors to visitors, and have formed the society Danish Castles & Manor Houses.

Out of the 50 or so castles and manor houses, more than 20 now provide accommodation with the fascinating cachet of nobility and heritage. A stay at one of the Danish castles or manor houses is a journey into Denmark’s history. Guests sleep in four-poster beds with stately interiors, in great halls beneath old vaulted ceilings and take strolls in exquisite grounds.

Events and exhibitions

A large number of Danish castles open their gates to stately grounds or grand halls displaying the finest collections of art or antiques. Over the year they also provide an atmospheric setting for concerts, exhibitions and cultural happenings in halls and castle gardens. Indeed, many castles are now entirely given over to their status as museums.
