Receive, triage, sanitize, store, dispatch, discard. These were some of the verbs used to conjugate the thousands of lives that came in the putrid womb of the slave ships to Brazil. If they arrived alive, and if their destination was Rio de Janeiro s harbor, between 1771 and 1833, African men and women would continue their survival path in the Valongo market, where they were prepared and exposed to public sale, - transformed into object, commodity and currency - tirelessly negotiated in the various barracks scattered in the bucolic village of white houses with red roofs in the parish of Santa Rita. The Valongo, supported by a necropolitic system that had the normatization of violence and the production of death, physical and social, as means of exercising sovereignty, constituted itself spatially as a set of urban equipment that functioned in an integrated way in the task of production and distribution of slave labor to various parts of the continent. Taking this scenario as a starting point, the present work develops as an investigation of the social, political and cultural processes that led the spatial consolidation of Valongo as a commercial complex, seeking in its material and symbolic expression the bases for forging a new concept that encompasses the necropolitic function of constructed environments: the necroarchitecture.
