The abbey of Saint-Andre-le-Bas was founded in the 8th century by Duke Ansemund. The church was originally a chapel of the palace of kings of Burgundy built in the end of the 9th century. The abbey flourished in the High Middle Ages.
The troubles of the Hundred Years' War and the competition of the new religious orders reduced the power of the convent and it was unable to recover from the Wars of religion. The monastery was dissolved in the late 18th century. The abbey church, built in the 11th century, became a parish church and the convent buildings were sold and partly dismembered. The church, the bell tower and the cloister are still remarkable for their harmonious Romanesque sculpted ornementation.
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.
