Besides the modern oral history, several endogenous and exogenous educational actions were accomplished, having as main focus to sensitize the internal public. All of this processes were accomplished through liberating education and an integrative museology. The experiences passed through to everyone involved in these museum processes, we brought the perspective of Sociomuseology to a federal and traditional museum. The submerged history is brought to this academic work through the methodology of oral history, the education actions were developed in many different ways and were monitored, registered and analyzed through action-research and the generative management was implemented. An institucional history document was produced with the voices of the internal public as the bond between the past time, present and desire for the future. The museum was transformed into a great liberating educational action in which the employees became agents of the development of the institution and the community.
