Santiago Calatrava, the world acclaimed representative of the new generation of architects, has in the span of one year worked on 5 projects which reflect Berlin's new identity as a European metropolis at the end of the Cold War. Four of these are literally cross-border projects: the Kronprinzen and Oberbaum Bridges which will relink East and West Berlin and which will definitely be built; and theJahn Sports Parklocated in the former border patrol zone and new construction and renovation projects for the Reichstag adjacent to where the Wall once stood. These latter designs (and also the Spandau Station) will remain as plans. All these works visibly demonstrate how Calatravaovercomes not only topographical borders but also the conventional restrictions of his discipline.
