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:The Church of St Donatus name refers to Donatus of Zadar, who began construction on this church in the 9th century and ended it on the northeastern part of the Roman forum. It is the largest Pre-Romanesque building in Croatia.
The beginning of the building of the church was placed to the second half of the 8th century, and it is supposed to have been completed in the 9th century. The Zadar bishop and diplomat Donat (8th and 9th centuries) is credited with the building of the church. He led the representations of the Dalmatian cities to Constantinople and Charles the Great, which is why this church bears slight resemblance to Charlemagne's court chapels, especially the one in Aachen, and also to the Basilica of San Vitale in Ravenna. It belongs to the Pre-Romanesque architectural period.
The circular church, formerly domed, is 27 m high and is characterised by simplicity and technical primitivism.
