Expo 67 pavilions Expo 67 pavilions The Expo 67 International and Universal Exposition featured 90 pavilions representing Man and His World, on a theme derived from , written by the famous French pilot Antoine de Saint-Exupéry. The exposition displayed many nations, corporations, industries, technologies, social themes, religions and designs, including the US pavilion, a geodesic dome designed by Buckminster Fuller. Expo 67 also featured Habitat 67, an urban modular housing complex designed by architect Moshe Safdie, whose units were purchased by private Montrealers after the fair was concluded, and is still occupied today. The most popular display of the exposition was the soaring
Geodesic dome the greatest volume for the least surface area. The dome was successfully adopted for specialized uses, such as the 21 Distant Early Warning Line domes built in Canada in 1956, the 1958 Union Tank Car Company dome near Baton Rouge, Louisiana, designed by Thomas C. Howard of Synergetics, Inc. and specialty buildings such as the Kaiser Aluminum domes (constructed in numerous locations across the US, e.g., Virginia Beach, Virginia), auditoriums, weather observatories, and storage facilities. The dome was soon breaking records for covered surface, enclosed volume, and construction speed. Beginning in 1954, the U.S. Marines experimented with helicopter-deliverable geodesic domes.
