About the Biosphere

You will be amazed by this iconic monument from the 1967 World’s Fair in Montréal.

History of the Biosphere

The Biosphere, an ecobuilding

The Biosphere was already considered a green building when it was renovated in 1995. After you visit the Biopshere's interactive exhibits on major environmental issues, discover the museum's various green technologies to learn more about alternatives and day-to-day solutions.


As the only environment museum in North America, the Biosphere's mandate is to raise awareness as well as to encourage citizens to take action and get involved in environmental issues. The museum distinguishes itself by its interactive and educational exhibits as well as animated activities which are aimed at increasing understanding of major environmental issues such as air, water, biodiversity, climate change, sustainable development and more.

Illuminated Biosphere

The Biosphere is more than a museum; it is a Montréal icon. That is why, after the festivities of Montréal’s 375th anniversary, Canada’s 150th, and, of course, Expo 67’s 50th, the structure is now illuminated—much to the delight of Montréal residents and tourists alike. Until 2037, the sphere will be lit up at nightfall and will change colours with the seasons. To reflect the passing of time, slow variations in colour and hue will transform its appearance. This initiative is part of the overall vision for the 2017 celebrations: to create a lasting legacy for Montrealers.

Illuminated mosaiculture

Since summer 2018, the Biosphere’s mosaiculture “We Are All of the Same Earth” embellishes the pool of water at the museum entrance. This plant sculpture represents the Earth and symbolizes the need to live in harmony with nature. The sculpture is also a gathering place for birds that like to perch there for a rest. An impressive number of plants in a variety of colours covers the surface of the mosaiculture. These represent our planet’s oceans, continents and ice-covered areas.

New in 2018 and for our visitors’ enjoyment, the sculpture will be illuminated after sunset. This new feature will blend harmoniously with the Biosphere’s illumination, which adds to the beauty of Montréal nights.
