The first architect to introduce the contemporary European architectural tendencies in Viborg was Uno Ullberg (born 1879 in Viipuri, died 1944 in Helsinki), a graduate of the Helsinki Polytechnic Stadia. In his function as Viborg’s main architect during the interwar-period, Ullberg designed a number of public buildings; among them such outstanding works as the Viipuri Art Museum and Drawing School, the Municipal Pawn Office (Viipuri Panttilaitos Oy) and the Provincial Archives Building.
The Municipal Pawn office (built 1931) refers with its white-stuccoed facades and its remarkable extremly simplified bands of windows to the architectural principles of the Bauhaus.

The Viipuri Art Museum and Drawing School (1930) reveals some reductiv Classicism elements such as the twin-row colonnade of pillars supporting an architrave with half-oculi. This architectural masterpiece is considered to be one of the signal works of the Nordic Classicism.
