パリ改造
The Eiffel Tower, built to serve as the grand entrance to the 1889 World's Fair held in Paris, became the accustomed symbol of the city, to its inhabitants and to visitors from around the world. Paris hosted another successful World's Fair in 1900, the Exposition Universelle. Paris had been profoundly changed by the Second Empire reforms to the city's architecture and public amenities. Haussmann's renovation of Paris changed its housing, street layouts, and green spaces. The walkable neighbourhoods were well-established by the Belle Époque.
