The Academy of Sciences edifice was built after World War II, between 1951 and 1961, collecting the necessary financing from the newly established kolkhozes in Latvia and - as further expenses increased, collecting the finances as 'voluntary donations' deducted from the salaries of the Latvian rural population.
The building is decorated with several hammers and sickles as well as Latvian folk ornaments and motifs. The spire originally was decorated with a wreath and a five pointed star, which was removed after Latvia regained independence in 1991. Being 108 metres tall, it was the first skyscraper in the republic and was the tallest building until the construction of the Swedbank Headquarters in Latvia.
The building, designed by Osvalds Tīlmanis, Vaidelotis Apsītis, and Kārlis Plūksne, is a cousin to similar Stalin-era skyscrapers, which were representative of what became known as Stalinist architecture (sometimes referred to as Socialist Classicism). The architecture of the skyscraper resembles many others built in the Soviet Union at the time, most notably the main building of Moscow State University. Local nicknames for this building include Stalin's birthday cake and the Kremlin.
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.
