Exploring the Ancient Maya City and Protected Tropical Forests of Calakmul, Campeche

The Ancient Maya City and Protected Tropical Forests of Calakmul, Campeche, situated in the heart of the Yucatan Peninsula, offers a unique blend of historical and natural wonders. Inscribed as a UNESCO World Heritage Site in 2002, this significant location provides valuable insights into the rich cultural heritage of the ancient Maya civilization while preserving the diverse tropical ecosystems that thrive within its boundaries.

UNESCO Description of the World Heritage Site

The site is located in the central/southern portion of the Yucatán Peninsula, in southern Mexico and includes the remains of the important Maya city Calakmul, set deep in the tropical forest of the Tierras Bajas. The city played a key role in the history of this region for more than twelve centuries and is characterized by well-preserved structures providing a vivid picture of life in an ancient Maya capital. The property also falls within the Mesoamerica biodiversity hotspot, the third largest in the world, encompassing all subtropical and tropical ecosystems from central Mexico to the Panama Canal.

UNESCO Justification of the World Heritage Site

Criterion (i): As a whole, the area is unique in that it preserves largely intact remains of the relatively rapid development of the Maya civilization in a hostile environment of tropical forest. The information available for research is vital for understanding multiple aspects of Maya culture and its evolution in the central lowlands of the Yucatan peninsula. The archaeological sites in the area constitute remnants of at least 1500 years (from ca. 500 B.C. to A.D. 1000) of intensive population growth and evolution of social complexity, conditioned by a successful adaptation to the inhospitable natural setting and accompanied by technological achievements and cultural development in general, which is reflected in the architecture, hieroglyphic writing, sculpted monuments and fine arts.

Criterion (ii): Pertaining to the Preclassic and Classic Maya civilization, the cultural aspects of the property include a mixture of autochthonous developments and exchange of ideas with the neighbouring regions. The creative combination of different traditions resulted in specific architectural styles, fine arts and modifications of natural landscape. While Calakmul, the largest site in the area, displays 120 commemorative stelae with relief carvings, including hieroglyphic inscriptions with important information on regional political history and territorial organization, a number of monuments of this kind have also been found at other major and medium centres, including La Muñeca, Uxul, Oxpemul, Balakbal, Champerico, Altamira and Cheyokolnah.

Criterion (iii): The property witnessed an unprecedented growth of an extraordinary civilization, which came to an abrupt end at the end of the Classic period. Considering that, after the dramatic population decline evidenced in the abandonment of virtually all the settlements in the 9th and 10th centuries A.D., the area has ever since remained practically uninhabited and has suffered little recent intervention, it represents an exceptional testimony to a long-living civilization and offers a unique opportunity to understand both the foundations of its florescence and the causes of its collapse.

Criterion (iv): The archaeological sites in the property contain some unrivalled examples of Maya monumental architecture, mostly pertaining to the so-called Peten tradition in the core area and the Rio Bec style confined to its north-eastern fringes. While the first is exemplified by palaces and huge temple pyramids at sites such as Calakmul, Yaxnohcah and Balakbal, which mirror the growth of social complexity during the Preclassic and Early Classic periods, the second represents a Late Classic development, characterized by false pyramid temples, normally in the shape of twin towers, and stone mosaic façade decorations. Since the epigraphic records show that the Classic period political geography of the area was overwhelmed by the Kaan, one of the most powerful royal dynasties, which in the Late Classic moved its capital city from Dzibanché to Calakmul, future research, is expected to clarify whether, or to what extent, the political domination of the Kaan dynasty, and its alliances and rivalries with the neighbouring polities, are reflected in the diverging trajectories of cultural development.

Criterion (ix): The mature tropical forests of Calakmul provide extraordinary evidence of the long-standing interaction between man and nature, insofar as they display a floristic composition and structure largely resulting from thousand-year old Maya agricultural and forestry practices, which intertwine processes of human selection and regeneration of natural systems, both considered traditional management practices among native communities still inhabiting in the buffer zone and surrounding areas. These processes resulted in a complex mosaic of tropical forests communities which allows complex ecological and trophic networks. It is also an important area for water recharging for the whole Yucatan Peninsula, a key factor in the development of the Maya Culture in the Ancient City of Calakmul and its surroundings.

Criterion (x): The tropical rain forest vegetation of the Property and the region of Calakmul, developed under particular seasonal dry conditions, contains a rich biodiversity and critical habitats for a number of endemic and threatened species and populations. The species are adapted to particular geomorphological and environmental conditions, such as the reduced availability of water and moisture, the presence of forest fires and hurricanes, and karst soils; conditions that impose strong limitations on the growth of plants characteristic of moister tropical forests. The area contains the greatest abundance of wildlife and the highest diversity of mammals in the Mayan Region; it is home to two out of the three species of primates, two out of the four species of edentates, and five out of the six feline species (cats) existing in Mexico.
