It reconsiders one of the defining features of urban life, of energy and exuberance that characterise the areas of the centre-dins of a framework of globalisation and contemporary change. It analyzes the emblematic centers of global cities through individual case studies from Europe, Asia, Africa, Latin America and the United States, taking into account the problems of function, population, images, and growth. 360 p.: B/w, 23x15 cm., paperback
