Ilmmünster Abbey was formerly a collegiate foundation and originally a Benedictine monastery. The original site was a Benedictine monastery, founded in about 762 by the brothers Adalbert and Otker, traditionally supposed to be members of the Huosi, an ancient Bavarian noble family. The monastery was dedicated to Saints Arsatius, whose relics were here, and Quirinus, whose relics were at Tegernsee Abbey, founded by the same brothers, to which Ilmmünster was affiliated.
A collegiate foundation was also set up here in 1060. In 1493, the monastery was transferred to the Frauenstift in Munich, leaving the site for the Kollegiatstift. The property and assets were sold off in 1802 during secularisation, but the impressive church remains.
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.
