This article is the result of the experience as a teacher and historian, and especially of the doctoral thesis, defended in the year 2017, through the Graduate Program in Education and Contemporaneity at the State University of Bahia, construction of a 3D modeling solution for the São João da Bahia Theater, considered as a pole and reflection of the praxis of the Savior of the Nineteenth and Twentieth centuries. The conception was developed from the problem of the inexistence of a modeling in the socio-constructivist perspective for the São João da Bahia Theater. In this way, the research aimed at possibilities for the subject, understood here as intellectual in the Gramscian perspective, to be a historian of oneself (subject subject), to build new knowledge (metacognition) through meaningful learning, mediated by the practice of visitation and interaction with the museum proposed.
