摘要：This paper seeks to understand and to interpret the solutions of the transformation, permanence, development, reorganization and consolidation processes of the urban matrix of the city of Porto between the second half of the 18 th century and the first half of the 20 th centur y. The intrinsic relationships between Porto's expansion and the newly built areas are clarified through the analysis of the main urbanistic studies and plans, since the action of the Almadas, and, particularly, since the plan implemented by the Board of Public Works of Porto (.Junta das Obras Públicas do Porto.), from 1763, to the Regulatory Plan for the City of Porto (.Plano Regulador da Cidade do Porto.; 1952).The relationships between the succession of plans are analysed, highlighting the evolution of the ways of planning the city, which culminate in a global vision of it, from the perspective of a territorial planning based on the principles of the Modern City.
