Constructed as the epitome of the future and the central featured pavilion at Montreal’s Expo 67, R. Buckminster Fuller’s geodesic dome is now 50 years old. Known as the Biosphere, the structure was the hit of the 1967 World’s Fair. Enclosed with trapezoidal acrylic inserts in the metal open-lattice structure and backed by a system of operable shades, the Biosphere exhibited all the hallmarks of futuristic design in the upbeat 1960s.
