The Instituto Nacional de Antropología e Historia (INAH, National Institute of Anthropology and History) is a Mexican federal government bureau established in 1939 to guarantee the research, preservation, protection, and promotion of the prehistoric, archaeological, anthropological, historical, and paleontological heritage of Mexico. Its creation has played a key role in preserving the Mexican cultural heritage. Its current national headquarters are housed in the Palace of the Marqués del Apartado.
INAH and the Instituto Nacional de Bellas Artes y Literatura (INBAL) are tasked with cataloging and protecting monuments and buildings regarded as cultural patrimony. INAH is entrusted with 'archaeological' (pre-Hispanic and paleontological) and 'historical' (post-Conquest 16th to 19th centuries) structures, zones and remnants, while INBAL is entrusted with 'artistic' buildings and monuments (properties that are of significant aesthetic value as deemed by a commission). Worthy edifices are catalogued in the Registro Público de Monumentos y Zonas Arqueológicos e Históricos (Public Register of Archeological and Historic Monuments and Zones).
