Biosphère is at 160 ch. Tour de-l'Isle on Île Ste-Hélène (M: Jean-Drapeau). This geodesic structure, the largest building of its kind in the world, reproduces more than three-fourths of a sphere and was originally constructed to house the U.S. pavilion at Expo 67. Inside, a museum features interactive exhibits and live presentations delving into environmental issues, including those pertaining to the atmosphere as well as to natural resources and their consumption. Outside a series of huge photographs features a variety of Canadian landscapes.
Guided tours are available. Picnicking is permitted.
