El lenguaje de las ciudades

A city is made by people. It has a distinctive identity, which consists of much more than a mere collection of buildings; climate, topography, and architecture all contribute to that distinction, as do its origins. What's fascinating is that all these elements don't always produce the same results: many cities have a river, but the Seine is unique, an essential part of what makes Paris different from Berlin. Hong Kong is a commercial city, and so are Dubai and Hamburg, but they are all distinct, unmistakable. Every city is a unique experience. Most of us live in cities, but do we know what makes a city a city? Is it a place... or an idea? How should we define the city today, as it evolves in the 21st century?
