Within the broad context of the crisis in the prison system in Brazil, with serious violations of human rights and human dignity, specificities characterize the issue of female imprisonment, since being imprisoned means breaking up with your family and being away from your home and your children, who will be cared for by others or sent to an institution due to the lack of appropriate spaces for this purpose. The aim of this final graduation project is to draw up a preliminary design for a mother and child penitentiary for the state of Alagoas, which works to re-socialize the inmate through motherhood and guarantees the child the right to be close to their mother, responding to the problems involved in this space, using humanized architecture, which "seeks to channel the human need for enriching, living and healthy environments" (BARROS, PINA, 2011). The result of the project shows that this architecture, combined with the parameters considered humanizing by Kowaltowski (1980) in the process of developing the architectural project, can minimize the conflicts found between this apparently antagonistic pair: humanization x security.
