The Hemisferic - Designed by award-winning architect Santiago Calatrava, this building is a Planetarium, a Laserium and an IMAX Theatre all rolled into one. It offers documentaries and an exploration of the universe. A laser show (with changing programs) runs on a 47-square metre (900 square feet) concave IMAX screen, with the soundtrack in four languages and six-channel stereo. The Hemisfèric was inaugurated on 16th April 1998 and was the first building in the City of Arts and Sciences to open its doors to the public.
