The building originally formed an enclosed structure of steel and acrylic, 76 meters (250 feet) in diameter and 62 meters (200 feet) high. A complex system of shades was used to control the internal temperature. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ The architects for the interior exhibition space were known as the Cambridge Seven.

The building included a 37-meter-long escalator, the longest ever built at the time. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ 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. ~ ~ ~ ~ ~ ~ ~ ~ ~ ~ Biosph?re museum site ~ ~ ~ ~ ~ ~ ~ ~ ~ ~
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.
