Expo 58, also known as the Brussels World’s Fair (Dutch: Brusselse Wereldtentoonstelling, French: Exposition Universelle et Internationale de Bruxelles), was held from 17 April to 19 October 1958.[1] It was the first major World's Fair after World War II.Nearly 15,000 workers spent three years building the 2 km2 (490 acres) site on the Heysel plateau, 7 kilometres (4.3 mi) northwest of central Brussels, Belgium. Many of the buildings were re-used from the Brussels International Exposition of 1935, which had been held on the same site.
