Santiago Calatrava is world-renowned as an engineer, sculptor, and artist. From the Olympic venues in Athens 2004 to the underground station at the World Trade Center in Manhattan, he has achieved remarkable aesthetic and engineering feats. Calatrava's creations show influences ranging from Leonardo da Vinci's studies of nature to NASA's spacecraft design. Aerodynamic associations, natural forms, and human movements are the starting points for many of his projects, reflecting his particular interest in the interplay of balance and dynamics. This updated monograph explores Calatrava's buildings through detailed entries, photographs, and his unique watercolors. It includes his entire body of work to date, including recent projects such as the Mediopadana station in Reggio Emilia, Italy, the Museum of Tomorrow in Rio de Janeiro, and the tower currently under construction.
