Expo 64

The Swiss national exposition of 1964 (French: Exposition nationale suisse de 1964), usually shortened to Expo 64, was a world's fair held in Lausanne, more specifically in Vidy and the neighbouring Vallée de la Jeunesse, between 30 April and 25 October 1964.

Expo 64 was directed by Gabriel Despland, with Alberto Camenzind as chief architect, Edmond Henri as administrative director, and Paul Ruckstuhl as financial director. The syndic of Lausanne, Georges-André Chevallaz, was also part of the direction committee.
