The book seeks to contribute to instigate the discipline of architecture on both sides of the Atlantic, based on reflections on the relations between Brazil and Portugal at a time in which both countries are undergoing intense transformations, under the pressure of contemporary globalization processes and the alarming crises that follow, urgently imposing the need for critical thinking. The authors of the texts accepted the provocation to reflect - individually or in dialogues with their overseas peers - on the conditions of architectural production, the ongoing urbanization processes and the cultural and urban policies of the two countries, without hiding the impasses that are revealed in the most evident crisis in Brazilian architecture, but also amidst the strength of contemporary Portuguese architecture.
