The Burgkirche ('castle church') is one of the largest and most imposing fortified churches in western Germany. The church is surrounded by a cemetery, which is surrounded by walls. The Romanesque tower of the church with Gothic battlements and turrets is the oldest part of the church, which was built in several phases in the late Gothic period. The restored stained glass windows and paintings in vaults - both from the 15th century - are worth of seeing. The church served as a graveyard of local nobility and has lots of interesting tombs.
References: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.
