City squares of the world

Urban squares are the greatest anthropological devices of the Western world, marvelous historical documents of towns and cities, the stratified evidence of passing centuries, the material testimony of the lay, religious and artistic actions of a population.
Squares, the quintessential synonym of public and collective space, are described in the volume from those of the Middle Ages, in other words, the time when the "piazza" began to specialize for its end purpose, up to the most contemporary of design.
