Montreal Biosphère

It looks like a bubble of water in the middle of nowhere but actually The Biosphère is a museum in Montreal, Canada, dedicated to the environment. It is located at Parc Jean-Drapeau on Île Sainte-Hélène in the former pavilion of the United States for the 1967 World Fair Expo 67. It offers interactive activities and features exhibits concerning major environmental issues related to water, climate change, air, eco-technologies and sustainable development.
