Montreal Biosphere (Canada)
The Biosphère is a museum in Montreal dedicated to environment. The architect of the geodesic dome was Richard Buckminster Fuller. The building originally formed an enclosed structure of steel and acrylic cells, 250 ft in diameter and 200 ft high. A complex system of shades was used to control the internal temperature. The building included a 37-metre-long escalator, the longest ever built at the time.
