This article is a result of an investigation in urban history that it investigated specifically on a punctual fact happened in the Bogota of 1939, the demolition of the former convent of Santo Domingo. Work that opened an immense door, the urban history of Bogota, on which we do the first approximation in the one that examines inside the conceptual frames proposed for the urban history, the narrow existing relation between history of the architecture and urban history and exercises of analysis observe and emphasize that they fuse in an indissoluble way the problem of the form and the architecture of the city with the conditions and social plots that sublie after this one.
