This work considers historic farms of Rio Paraíba Valley as value spaces, and it seeks to identify them as meaningful sites for their importance in the region in 19th century, and also for their role in organizing guided tours and producing narratives about the slavery history. The aim was also to discuss the public production of history and the construction of a historical consciousness related to slavery. Finally, the work proposes a plan of a guided tour to the quilombo São José da Serra, in Valença / RJ, a territory that was a space of struggle and resistance. The plan will highlight the role played by Africans and descendents in slavery times and today. Therefore, we seek to investigate how history is understood and performed outside the academic world, and how the guided tours contribute to the construction of a historical knowledge related to slavery, in order to explore the multiple fields of activity for the historians.
