In Sweden, modern architecture was preceded by a group of architects who practiced an extremely strict and austere type of Neo-classicism. During the 1910s and 1920s, Gunnar Asplund and Ivar Tengbom were two of the most well-known examples, contributing to the style that became recognized globally as "Swedish Grace." During the 1930s, Swedish architecture took on more nationalistic themes, with art deco and neoclassical styles being particularly popular. The end of World War II saw a return to the international style, this time influenced by American architecture. Today, there are many famous buildings all over Sweden, some designed by internationally renowned architects such as Eero Saarinen or Charles and Ray Eames. However, not all Swedes are fans of their country's architecture. A survey conducted in 2014 asked people to rate the quality of buildings across Sweden. Only 14% of respondents rated the quality of architecture in Sweden as good or excellent. The rest either said it was fair or bad. The survey also found that only 13% of respondents felt confident describing what kind of architecture they saw in Sweden. Around half of respondents couldn't identify any specific style of architecture, while 35% said they saw elements of both traditional and contemporary styles. There are several factors that may have contributed to the public perception of poor quality architecture in Sweden.
