Architecture has always been the faithful mirror of society's most important transformations. By the same token, modern architecture, which has broken away from established trends and has a wealth of technology at its disposal, affirms new values that cater to the psychological and spiritual progress of humanity. This innovative work's timeline starts with the end of World War II and the ensuing rift in international architecture and urban planning. Through highly informative images, the book conveys the new representative languages of the postwar era, with its need for reconstruction and its quest for a new monumentality, and examines the new trends that emerged up to the beginning of the 21st century. Photography has been used as an extraordinary medium to explore this new world of architecture, with its ethereal and sometimes colossal forms that are utterly rational and surprisingly well balanced. Essays written by experts, accompanied by high-quality photographs that perfectly capture the multifaceted spirit of modern architecture, illustrate the complex tapestry of the international movements of the 20th century, from technological expressiveness to a new modernity, investigating meg-astructures, advanced technology, postmodernism, minimalism and deconstructionism. Sprawling museums and hyperfunctional airports, enormous shopping centers and futuristic libraries, sports arenas and immense university complexes are presented - along with their brilliant creators - on this surprising journey through forms, materials, colours, ideas and symbols. The outcome is an uncommon portrait of our world and the way architecture interprets it.
