Under different conceptions and categories, the original traces and architecture of cities are first and foremost a concern after the Second World War. Since then, and faced with a growing global tourism industry, the city has become an object of mass consumption and real estate investment, which, in order to be digestible, has been required to define and characterise it. Although there have already been short attempts in Mexico since the 1930s, the introduction of policies and instruments for their preservation starts four decades later. Various positions were deployed in this search. The sharp contradiction would, however, be summarised in that in which the institutions responsible took a role beyond the proxy which, in some cases, led to the replacement of the knowledge and wills of society. Taking Tepic Nayarit’s historic Vibral City as its object, from an interpretative historicist approach, this work describes and reflects on the consequences of subjecting it to an naive model of Mexican province, as well as the possible implications that this taxation has on the natural development of the urban-architectural image of this middle city of the west of Mexico.
