The drawn up one predominates of irregular apples. This brings with himself that are an increase of the near space, where the numerous present churches in the city are based. The conservation of all these values in this city was possible thanks to its isolation, to its slow growth and the lack of controls in its urbanization.

To all the previous one it is necessary to add to the combination of architectonic styles and numerous churches located in the places and located between the different districts. The name whereupon also it is known this city there: the city of the churches. It is certain that one affirms that the city is colonial, but in fact only 8% of the buildings have this characteristic, (arcs, truncated pilasters, eaves of prop, tinajones and ceilings of armor), whereas the outer aspect predominates the eclecticism.
