Coloma castle was built around 1515. It is a square building with square corner towers and a pear-shaped roof and surrounded by a moat. The castle has been completely restored and serves as a municipal cultural center. In the castle park are some interesting buildings such as the former carriage house of 1731 (now a cozy tavern) and a garden pavilion with stair tower. The Rose Garden of Coloma is the largest in Europe. The garden has an area of 15 hectares.
Rosenborg Palace was built in the period 1606-34 as Christian IV’s summerhouse just outside the ramparts of Copenhagen. Christian IV was very fond of the palace and often stayed at the castle when he resided in Copenhagen, and it was here that he died in 1648. After his death, the palace passed to his son King Frederik III, who together with his queen, Sophie Amalie, carried out several types of modernisation.
The last king who used the place as a residence was Frederik IV, and around 1720, Rosenborg was abandoned in favor of Frederiksborg Palace.Through the 1700s, considerable art treasures were collected at Rosenborg Castle, among other things items from the estates of deceased royalty and from Christiansborg after the fire there in 1794.
Soon the idea of a museum arose, and that was realised in 1833, which is The Royal Danish Collection’s official year of establishment.
