Sebastiao Calatrava conceived the building as an oversized human eye – the Eye of Wisdom, intended to symbolize the audiovisual experience of visitors watching the performances. The 100-meter-long oval roof houses a 3D IMAX theater and the surrounding Carl Sagan Perimeter Ring, named in honor of the American physicist.
