The infrastructure of the colonial territories obeyed the logic of economic exploitation, territorial domain and commercial dynamics among others that left deep marks in the constructed landscape. The rationales applied to the decisions behind the construction of infrastructures varied according to the historical period, the political model of colonial administration and the international conjuncture. This congress seeks to bring to the knowledge of the scientific community the dynamics of occupation and transformation of colonial territory, especially related to and resulting from the war effort, which involved not only the agency of architecture and urbanism but also of military apparatus, and its repercussions in the same territories as independent countries. Colonial infrastructures will be addressed to question, for instance, how housing production during armed conflict has conditioned future spatial models of the independent countries or what options taken by colonial administrations were abandoned or otherwise strengthened after independence.
