In the Russian Empire, it was the capital of the Kaunas Governorate from 1843 to 1915.[10] During the interwar period, it served as the temporary capital of Lithuania, when Vilnius was seized and controlled by Poland between 1920 and 1939. During that period Kaunas was celebrated for its rich cultural and academic life, fashion, construction of countless Art Deco and Lithuanian National Revival architectural-style buildings as well as popular furniture, interior design of the time, and a widespread café culture.[1] The city interwar architecture is regarded as among the finest examples of European Art Deco and has received the European Heritage Label.[11][12] It contributed to Kaunas being designated as the first city in Central and Eastern Europe as a UNESCO City of Design,[13][14][15] and also to becoming a World Heritage Site in 2023 as the only European city representing large scale urbanization during the interwar period and versatile modernism architecture.[16]
