Among Asplund's most important works is the
Stockholm Public Library, constructed between 1924 and 1928, which stands as the prototypical example of the
Nordic Classicism and so-called
Swedish Grace movement. It was particularly influential on the proposal submitted for the competition for the design of the
Viipuri Library in 1927 by Finnish architect
Alvar Aalto, who regarded Asplund as his mentor. Another important work is the extension of the
Gothenburg City Hall Extension building which Asplund started on 1913 and finished 1937 - it shows his transformation from neo-classical to
functionalist architect, a transformation in parallel with other European modernists like
Erich Mendelsohn. Asplund collaborated with architect
Sigurd Lewerentz in the design of
Skogskyrkogården, a cemetery which is a
UNESCO world heritage site, created between 1914 and 1940. They were also the main architects for the temporary
Stockholm International Exhibition (1930). Although temporary, the modernist, exposed-glass-and-steel-frame Entry Pavilion at the fair was internationally influential. In fact, it was influential already before its completion, having an influence on the much smaller Turku Fair in Finland, designed by
Alvar Aalto and
Erik Bryggman, who had travelled to Stockholm to see its construction. Gunnar Asplund is considered perhaps the most important modernist Swedish architect and has had a major influence on later generations of Swedish and Nordic architects. == Our architectonic concept of space ==
