Nonnberg Abbey is a Benedictine monastery in Salzburg founded ca. 714 by Saint Rupert of Salzburg. It is the oldest women's religious house in the German-speaking world. Its first abbess was Saint Erentrudis of Salzburg, who was either a niece or a sister of Saint Rupert.
The abbey was independent of the founding house from 987 and was re-built in about 1000. This building was largely destroyed in a fire of 1423. Reconstruction took place between 1464 and 1509.
The nunnery′s church Maria Himmelfahrt is Salzburg′s oldest church dedicated to the holy Virgin Mary and is one of the most significant churches of the city. It was built in late-gothic style with three naves from 1464 to 1506. In 1624 the church was enlarged by the addition of three side chapels. A refurbishment in the Baroque style took place in the 1880s. The church contains a Romanesque crypt that visitors should note, with the tomb of St. Erentrudis. The entrances to the crypt are in the side-naves.
Through Maria Augusta Kutschera, later Maria Augusta von Trapp, who was a postulant in the abbey after World War I and whose life was the basis for the film The Sound of Music, the abbey has acquired international fame. The Mother Abbess during Maria's time at Nonnberg was Sister Virgilia Lütz (1869-1949).
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.
