The Canadian Pavilion at Expo 67 in Montreal featured an inverted pyramid structure as well as a walk through an attraction called the "People Tree." The pavilion had its highest single-day attendance on Canada Day (July 1), 1967.[1]
The pavilion's large inverted pyramid was called Katimavik, which is the Inuit word for "Gathering Place". The pyramid was nine storeys tall and supported by four columns. The building at its base housed a rotating theatre, which used moving wedge-shaped chambers to bring audiences from one screening to the next, making a complete revolution every half-hour. Smaller linked pyramids at ground level housed the exhibits "The Land of Canada," "The Growth of Canada" and "The Challenge to Canadians and Canada and the World." The pavilion was located on a 7½ acre (30,285 sq metre) lot near the southern end of Notre Dame Island.[1][2] It cost $24 million to build.[3] The inverted pyramid was a 1000-ton structure, with a hollow steel frame. Open to the sky, its four inner sloping walls featured giant sculptures of a sun dial, hour glass, compass and Kyogen and Haida masks.[4]
