Established from 1332 to 1339 as a foundation endowed by the wealthy patrician Konrad Groß for the elderly and needy. Considered the largest private endowment by any individual before 1500.
The Hospital of the Holy Spirit was established in 1332–39 by Konrad Gross, a wealthy patrician, for the care for the elderly and needy. It was the largest private endowment in the Holy Roman Empire up to 1500. After 1500 the building complex was extended over the Pegnitz according to plans by Hans Beheim the Elder. Two structures along the southern arm of the river and the north wall of the former hospital church with its polygonal ridge-turret survive.
From 1424 to 1796, the imperial regalia were kept in the hospital church (not reconstructed after the war). In the arcaded Kreuzigungshof, there are the central figures of Adam Kraft’s Crucifixion group (ca 1506/08) and the tomb monuments of Konrad Gross (d. 1356) and Herdegen Valzner (d. 1423).
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.
