Designed in the early 1960s, the original buildings incorporate [[Brutalist architecture|Brutalist]] designs. The building complex is made up of three main buildings connected by a series of [[bridge]]s and [[escalator]]s set in a parkland of over 100 acres.<ref name="Omand" />{{rp|78}} The buildings were constructed while avoiding removal or damage to the mature trees in the area, so that "the buildings seem to fit naturally into their environment".<ref name="Omand" />{{rp|78}} They follow the natural contours of the Don River ravine, into which the Centre descends. Ontario's only [[IMAX Dome]] theatre opened in 1996.<ref name="autogenerated1" />
The Great Hall is an event venue at the Ontario Science Centre and is home to ''Cloud'', a massive, computer-controlled [[kinetic sculpture]] by Toronto installation artist [[David Rokeby]], which consists of an array of blue and transparent squares that rotate in various ways to simulate the three states of matter: solid, liquid and gas.<ref>[{{Cite web|url=https://www.ontariosciencecentre.ca/Tour/Art-Installations/|title=Page Not Found | Ontario Science Centre: Art Installations<!-- Bot generated title -->]|website=www.ontariosciencecentre.ca}}</ref>
