A fire burned away the building's acrylic bubble in 1976, but the steel latticework remained.

A science museum on the theme of water was built in the Biosph?re in 1995. The new museum is a set of enclosed buildings designed by ?ric Gauthier, inside the original steel skeleton.

Geodesic dome: A geodesic dome is an almost spherical structure based on a network of struts arranged on great circles (geodesics) lying on the surface of a sphere. The geodesics intersect to form triangular elements that create local triangular rigidity and distribute the stress. It is the only man made structu...
