The Palace of Nations is the home of the United Nations Office at Geneva. It was built between 1929 and 1938 to serve as the headquarters of the League of Nations. The palace was at the time of completion the second-largest building complex in Europe after Versailles.
The Palace is located in Ariana Park, which was bequeathed to the City of Geneva in 1890 by Gustave de Revilliod de la Rive, on several conditions: i.a. that the park always remain accessible to the public and that he be buried in the park. The park also contains a 1668 chalet.
Beneath the Palace of Nations's foundation stone is a time capsule containing a document listing the names of the League of Nations member states, a copy of the Covenant of the League, and specimen coins of all the countries represented at the league's Tenth Assembly. A medal showing the Palace of Nations with the Jura Mountains in the background was struck in silvered bronze.
The building overlooks Lake Geneva and has a clear view of the French Alps.
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.
