This lecture explores the evolution of spatial territories from the city-countryside opposition to the urban context, focusing on three key elements: morphologies, centralities, and lifestyles. It discusses how advancements in transportation and communication systems have reshaped the spatial structure of territories, blurring morphological boundaries and promoting urban sprawl. The lecture also delves into the international reconfiguration of city influence and the challenges posed by ubiquitous urbanization, such as less spatially differentiated consumption patterns and the emergence of new metropolitan dynamics.
