Inspired by the shape of the human eye, Calatrava’s Planetarium and IMAX Theater is located in the heart of the City of Arts and Science. The “pupil” is the hemispherical dome of the IMAX Theater which is transformed into a globe through its reflection in the surrounding pool. The concrete socket of the eye incorporates an “eyelid” of vertical articulated metal slates which can be raised to permit views of the pool. The Príncipe Felipe Science Museum, also within the City of Arts and Science, is a spatial tour de force. Based on an asymmetrical repetition of tree and rib like forms, the Science Museum’s supporting framework of white concrete is filled with glass to admit ample daylight.
