The Abbey of Saint-Evroul is a former Benedictine abbey, today in ruins. Its name refers to its founder, Ebrulf (Evroul), who founded a hermitage in the forest of Ouche around 560. The abbey was rebuilt around 1000. Robert de Grantmesnil served as abbot of Saint-Evroul, which he helped restore in 1050. He had become a monk at Saint-Evroul before becoming its abbot. Orderic Vitalis entered the abbey as a young boy and later wrote a history of the abbey. Saint-Evroul was famed for its musical programme and eleven monks brought its musical traditions to the abbey of Sant'Eufemia (now part ot town of Lamezia Terme) in Calabria. The abbey was rebuilt again between 1231 and 1284. In 1628 it was closed and demolished finally in the early 1800s.
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.
