摘要：At the beginning of the 21st century, there are various social theories that speak of global changes in the history of human civilization. Urban models have been through obvious changes throughout the last century according to the important transformation that are pro-posed by previous general theories. Nevertheless global diversity contradicts the generaliza-tion of these theories and models. From our own simple observations and reflections we arrive at conclusions that distance themselves from the prevailing theory of our civilized world. New York, Delhi, Salvador de Bahia, Bruges, Paris, Cartagena de Indias or Kath-mandu still have more internal differences than similarities.
