Montreal’s Rio Tinto Alcan Planetarium merges cutting-edge astronomy with sustainability, offering visitors an immersive cosmic experience in a LEED Platinum-certified design utilizing energy-efficient lighting, greywater recycling, and a green roof adorned with drought-resistant plants. As part of the Space for Life museum district, this planetarium is a reinvention of its 1966 predecessor, now embodying a bold architectural vision inspired by nature.

With dual 360° domes as metaphorical telescopes, it brings the mysteries of the universe down to Earth through state-of-the-art projections, interactive exhibits, and dazzling shows. With views from its panoramic room and versatile spaces for private events, the Rio Tinto Alcan Planetarium is both an architectural and scientific landmark that redefines our relationship with the cosmos and the planet.
