Brief SynthesisThe Historic Fortified Town of Campeche, located in the State of Campeche, was founded in the 16th century on the coast of the Gulf of Mexico, in the Maya region of Ah-Kim-Pech by Spanish conquerors. Criterion (ii): The harbour town of Campeche is an urbanization model of a Baroque colonial town, with its checkerboard street plan; the defensive walls surrounding its historic centre reflect the influence of the military architecture in the Caribbean. The area of historic monuments is a coherent reflection of colonial architecture. AuthenticityThe area of historic monuments and the system of fortifications have a high degree of authenticity because of the small number of transformations and interventions. A Federal Decree of 1986 lists the area of historic monuments of Campeche and places it under the authority of the National Institute of Anthropology and History (INAH), to function as a regulator and to authorize any kind of intervention in historic monuments within the historical monuments area the exterior and interior of the historical monument.
