Cinesphere is the world's first permanent IMAX movie theatre, built in 1971. Its design is of a triodetic-domed structure, akin to a geodesic dome, similar to that of the later Spaceship Earth, the icon of Walt Disney World's Epcot theme park. The theatre is located on the grounds of Ontario Place in Toronto, Ontario, Canada.
