Like once the main towers of the cathedrals, skyscrapers are the dominant landmarks in the cityscape of today and thereby one of the most coveted sought after building assignments of creative architects. The design freedom of the contour and the plastic volume of the blob have long since superseded the purely orthogonal towers of the past. In addition to the most significant projects of recent years, the most spectacular towers still under construction, as well as path-breaking experimental sketches are presented by means of texts, planning material and illustrations. Comprehensive tables give the most important performance markers and provide information about the central subjects specific to this type of building, like the vertical development, safety and energy concepts.
