Charlet, E. C. L., & da Silva Furtado, J. V. (2024). In October 1843, the prisoners of the public jail of Belém were transferred to the São José building, a former convent built by the Franciscans, which had been occupied by the government after the expulsion of the missionaries from the Amazon. Later, this would become one of the main prison institutions in the capital of Pará between the imperial and part of the republican contexts, functioning as a prison until the end of the 20th century. In the context of its installation, a regulation was produced to guide its operation, dictating the measures of control and organization. In this paper, we analyze the prison regulation in dialogue with the debates about the prison reform of the Brazilian Empire thought in this context and the daily life in the prison in its first years of operation.
