Between 1984 and 1992 the Frenchman Pierre Nora coordinated the books called Lieux de Mémoire (Realms of Memory) to study national sentiment, analyzing the places in which the collective inheritance of France had crystallized, the principal places in which collective memory was rooted in order to create a vast topology of French symbolism. In several European countries the proposal of Nora has been followed but in the American continent it has not been widely applied to explain how the memory has been perpetuated, on writings, images, monuments, ceremonies, rituals, men or institutions. The realms of memory are an essential element to understand the identity of Mexican society, since they were a key piece in the construction of the national identity that was defined from the founding myth, as an independent nation, and supported by all those facts that helped to preserve Mexico as a free country. Used to build the history of a new nation, they contributed to disseminate, through a well-structured pedagogy, those cultural elements that make up identity, political affiliation and civic values. All this has as an aim to participate in the invention of a tradition that remembers only those historical facts that are considered keys in each epoch. In this way, the collective memory is directed towards a homogenization that responds to corporate and / or individual interests in each moment. The paper presented for discussion will analyze the conformation of the historical memory throughout the nineteenth century and the way in which it was materialized in Mexico, recognizing our own places of memory. It will be discussed by colleagues from different countries, specialists in places, identity and memory, to confront the original proposal with its application in other latitudes.
