Acesso em:.https://bdm.ufpa.br/handle/prefix/9328The commercial exploitation of sambaquis (shell mounds), which turned fossilized marine shells into raw material for quicklime, established itself as a key economic activity that sustained colonial architectural projects since the beginning of colonization, playing a role in the formation of several urban centers across Brazil. This research proposes to discuss one of the processes of human occupation at the mouth of the Pirabas River, in the Salgado region of Pará, which occurred during the second half of the 19th century, through the perspective of the exploitation of local sambaquis recorded by the scientist Domingos Soares Ferreira Penna. By engaging with authors who discuss the history of archaeology and related themes - such as the occupation of the Amazon - and analyzing newspapers from the period, it was concluded that the resignification of sambaquis from vestiges of a distant past into raw material for the lime industry was a determining factor in the formation of the first population center of São João de Pirabas. Consequently, the research found that sambaquis are intrinsic elements of the formation processes of the populations at the mouth of the Pirabas River across different periods of time.Acesso AbertoSão João de PirabasSambaquiIndústria caieiraEngenharia colonialShell moundLime industryColonial engineeringCNPQ::CIENCIAS HUMANAS::HISTORIA::HISTORIA DO BRASIL::HISTORIA REGIONAL DO BRASILTrabalho de Curso - Graduação - MonografiaAttribution-NonCommercial-NoDerivs 3.0 Brazil
