Over the last few centuries urban planning has evolved radically. The building of cities and towns has a complex and multifaceted history. Although urban planning has only been recognized as a distinct profession for less than a century, cities worldwide reflect the different elements of conscious design in everything from their layout to their functionality. In early times, cities provided a safe haven from outside forces and have been always been the center of government. With the introduction of modern aerial warfare, cities have become key targets for destruction rather than safe zones.

Consequently, over time the needs of cities changed. Architects have created some of the most influential urban designs in history to meet the needs of citizens. The infographic below reflects these changes from Giambattista Nolli's ''Nolli Map'' to Le Corbusier's ''Radiant City.''  Each of these plans has changed how we live, with each step in this urban revolution having had a significant impact on their societies and all over the world.
