Uno Verner Ullberg (1879 in Viipuri – 1944 in Helsinki) was a famous Finnish architect.
Educated in Helsinki, he returned to his home town Viipuri in 1906.
He drew most of his buildings in Viipuri, but during the last years of his life also in Finland's capital Helsinki.
Viipuri belonged until 1809 to the Kingdom of Sweden.
During 1809 - 1917 it was a part of the autonomous Grand Duchy of Finland.
It was the second largest city of independent Finland as of 1917.
After being conquered by the Soviet Union's red army in both 1940 during the Winter War and then again in 1944 during the War of Continuation, it then became a part of the Soviet Union under the Russian name Vyborg after the 1947 peace treaty in Paris, France.
When the Soviet Union disbanded itself in 1991, it became a part of Russia.
The style of his architecture covers the transition in architecture from so-called Nordic Classicism of the 1920s to Functionalism during the 1930s.
Ullberg is regarded as a leading architect of the Nordic Classicism period and was the first to introduce Functionalism to Viipuri.
Though his most notable buildings were constructed in Viipuri, he became famous not only in his native town but nationwide.
