Constructed in 1971 as part of the original Ontario Place, the Cinesphere is an important part of the closed park's architectural legacy. Built as the world's first permanent IMAX theatre, the structure also holds an important place in the history of film. Submitted to the UrbanToronto Flickr Pool by @ThetaState, today's Photo of the Day features the nighttime illumination of the triodetic-domed structure.
