There are shrinking cities, whether open and visible, or secret and hidden ones, all over the world, not only in the industrially-developed countries of Europe and America, but also (notwithstanding the growth of "megapolises" and "global cities") in Asia and Africa - and even in small countries such as Switzerland. A large number of locations were considered as subjects for the Shrinking Cities investigation, its exhibition and publications. The candidates finally selected were: Detroit, Ivanovo, Manchester / Liverpool and Halle / Leipzig.
Detroit is probably the largest (and in its cityscape most striking) example of a metropolis that is continually shrinking: a process that has been going on there for over fifty years.
