From an architectonic point of view the aim of this article was to study the main Wilkawain construction, in the Peruvian territory; to localize and to place it in Callejón de Huaylas, considering the geographic setting characteristics evaluating the timeline period registered by the archaeology, ancient Peru Middle Horizon as well as the threats and opportunities of the contemporary period for the archaeological monument.

The objective of this article is to study and present the official architectural images of the new Latin American nations through their pavilions. Two exhibitions in Paris have been taken as the scene of political representation, but with a very different character. While the Universal Exhibition of 1867 had a monarchical and imperial vision, the Universal Ex- hibition of 1889 housed a republican spirit, coinciding with the centenary of the French Revolution.
