Marienmünster is well known for the former Marienmünster Abbey Church with its organ, which is well worth seeing and hearing. Marienmünster Abbey is a former Benedictine monastery, dissolved in 1803. Founded in 1127, the monastery reached its peak in the 12th and 13th centuries. During the Thirty Years' War, the monastery and the church were badly damaged and had to be rebuilt from 1661 onwards. From 1965 to 2014, Passionists lived there and pastored the surrounding parishes.

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.
