Montreal Biosphere, Montreal

There’s nothing like a World’s Fair to inspire odd architecture. That’s exactly what happened for the 1967 World’s Fair in Montreal, when architect Buckminster Fuller designed this geodesic dome. His structure bubbles up from the trees on Saint Helen’s Island to 200 feet high and 250 feet in diameter. It was an enclosed structure until a fire in 1976 destroyed the outer layer. Today, the thin-shell structure is owned and run by Environment Canada as a museum, with interactive exhibits on biodiversity and climate change.
