The Electoral Palace (Kurfürstliches Schloss) in Bonn is the former residential palace of the Prince-Electors of Cologne. Since 1818, it has been the University of Bonn's main building in the city center, home to the University administration and the faculty of humanities and theology.
The palace was built by Enrico Zuccalli for the prince-elector Joseph Clemens of Bavaria from 1697 to 1705. The Hofgarten, a large park in front of the main building, is a popular place for students to meet, study and relax. The Hofgarten was repeatedly a place for political demonstrations.
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.
