The Biosphere is the former US pavilion from Expo 67, the 1967 world fair held in Montreal celebrating Canada's centennial.
The US Government donated the their pavilion, a geodesic dome designed by Buckmaster Fuller, to Canada after Expo 67 was over.
From 1968 to 1976 it went through several iterations including housing the world's second largest Aviary.
In 1976 a 15 minute fire lit by a welder's torch burned the clear acrylic exterior cover completely. The fire, while intense, did not damage the structure itself.
In 1996 it became the Biosphere, a federally owned museum dedicated to water. Subsequently in 2021 it was taken over by the City of Montreal as an environmental museum
