Buckminster Fuller as the US Pavilion for Montreal’s Expo 67. After the fair was over, the city of Montreal turned it into an experimental display biosphere. Fuller had wanted the steel structure to be assembled with bolts, but was overruled and in the rush they just welded it together instead. It had an acrylic sheathing, so in 1976 when they were repairing the structure - with welding torches rather than regular tools, as Fuller would have preferred - the sheathing of course caught fire and burned off, leaving only the steel lattice structure behind. The fire lasted only 20 minutes. The building was restored in 1996. #BRUTgroup photo via #isc20c https://www.instagram.com/p/Bqad6p8F4Dz/?utm_source=ig_tumblr_share&igshid=bf8lm1yorh2f
