Chucho's essey

For the research papper we are going to write I am thinking in a topic related with the conservation and restauration of ancient buldings in Mexico. I am not thinking in explainig what about with restauration and how the specialists, such as the architects, art historians, historians, etc., work on it. I would like to make some reflexions about how good is to restaure or conservte ancient buildings such as colonial churches, prehispanic structures, palaces, among others. It is necessary to state an historical context and see what happens with the revaluation of the old constructions, called the national patrimony, which started since the last decades of the 19th century. There are several positions about this complex situation among many authors. Some thinks the restaurations affects the image of the ancient monuments and others want to preserve them with different purposes, for example, to impede their destruction, and in the other side to use them like a bussiness. I would like to check some of them and try to see some examples of some sites chich are very common and famous in Mexico and in the world, such as Palenque, Chiapas.
