Originally published as "Caminando hacia la descolonización urbano-arquitectónica" in the third edition of Revista CLEA—an annual publication of the Coordinadora Latinoamericana de Estudiantes de Arquitectura (CLEA)—this article presents an introduction to the decolonization of spaces as a political, social, and methodological critique of the territorial, urban, and architectural praxis that has become established in our cities.
