Saint-Sever Abbey (abbaye de Saint-Sever) is a Benedictine monastery. It was founded at the end of the 10th century by William II Sánchez of Gascony. According to the monastic chronicles, this was as the result of a vow he made after the battle of Taller, in Gascony, in which he defeated the Vikings (982). In 1060, after a fire, the abbey was reconstructed on the model of Cluny under the direction of the abbot Gregori de Montaner. The Saint-Sever Beatus was the work of monks working under the direction of the same abbot; Abbot Gregori held the post from 1028 to 1072.
The abbey church is a Romanesque building from the 12th century with seven apses. The abbey was listed by France as a historic monument in 1911 and in 1998 it and other sites were jointly designated as the Routes of Santiago de Compostela in France World Heritage site.
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.
