The Montreal Biosphere is a museum dedicated to the environment operated by the City of Montreal. Located in Parc Jean-Drapeau on Saint Helen’s Island, the Biosphere is one of five museums in the city that focus on the natural world. The museum is housed inside a geodesic dome designed by the famed American architect Buckminster Fuller. The dome originally served as the American Pavilion during Expo 67. The Montreal Biosphere is the only museum in Canada exclusively devoted to educating the public about environmental issues.
