Biburg Abbey was a house of the Benedictines founded in 1132 by Konrad and Arbo von Sittling-Biburg. They were sons of the Blessed Berta of Biburg, who donated their castle to the Bishop of Bamberg for the purpose. The foundation was originally a double monastery for both men and women; the nunnery however burnt down in 1258 and was not re-built.
In 1555 the monastery was dissolved and the premises came into lay hands. In 1589 the Jesuit College of Ingolstadt obtained the buildings, which were taken over in 1781 by the Knights Hospitaller. In 1808 the monastery was secularised and passed into the possession of the Bavarian State.
The abbey church has remained mainly unchanged from its inauguration in 1140.
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.
