The Cahill Center for Astronomy and Astrophysics at Caltech brings together a dozen different scientific groups into one structure. The Cahill Center designed by Morphosis Architects, Inc. conceptually acts as an astronomical instrument. A vertical volume pierces the building, tilting it open to the skies and resulting in an occupiable telescope. The Center also physically and symbolically connects Caltech’s South Campus with the the original complex of Spanish and Mediterranean buildings that comprise the historic North Campus. A series of interior corridors that run north to south serve as stitches, reinforcing the connection and serving to direct circulation.
