Introduction: an atlas of the urban icons project

When the World Trade Center towers collapsed on 11 September 2001, many commentators noted that in their short lives, the towers had come to represent many things: American-led global capitalism, the United States and, most of all, New York City. Their brief role as a shorthand way of saying ‘New York City’ provoked us to ask about ‘urban icons’ more generally. But we did not need such cataclysm to provoke us to consider the topic of icons and their functioning in contemporary global culture. To help illuminate the usefulness of the concept of ‘urban icons’ we held an international conference in order to determine whether the category can be used as a conceptual grid for studying the intersection of visual culture and urban history.
