Riga, the present-day capital of Latvia, was at the time one of the
major cities of the Russian Empire. Art Nouveau architecture in Riga
nevertheless developed according to its own dynamics, and the style
became overwhelmingly popular in the city. Soon after the Latvian
Ethnographic Exhibition in 1896 and the Industrial and Handicrafts
Exhibition in 1901, Art Nouveau became the dominant style in the
city.[139] Thus Art Nouveau architecture accounts for one-third of all
the buildings in the centre of Riga, making it the city with the highest
concentration of such buildings anywhere in the world. The quantity and
quality of Art Nouveau architecture was among the criteria for including
Riga in UNESCO World Cultural Heritage.[140]
