Urbanism, as an intellectual movement, born from the confrontation of the urban problems that have gained visibility from the Industrial Revolution, has had as main object models development, theories and solutions that would make conceptions of planned cities. In specific moments of this trajectory, certain characters plan not only to plan a city, but rather a set of cities, i.e., the region. The works of the planners Ebenezer Howard, Patrick Geddes and Le Corbusier, along with the 1933 Athens Charter have established theoretical and conceptual bases for regional planning. Otherwise, in the epistemology of Milton Santos there is the basis of the contemporary geography with a rich reflection on the space, the region and man's interaction with his environment. This article briefly aims to establish a link between these timeless works and contribute to the discussion on the future of regional planning.
