Coba

Coba (Cobá) is an ancient Maya city on the Yucatán Peninsula, located in the Mexican state of Quintana Roo. The site is the nexus of the largest network of stone causeways of the ancient Maya world, and it contains many engraved and sculpted stelae that document ceremonial life and important events of the Late Classic Period (AD 600–900) of Mesoamerican civilization. The adjacent modern village bearing the same name, reported a population of 1,278 inhabitants in the 2010 Mexican federal census. The ruins of Coba lie 47 km (approx. 29 mi) northwest of Tulum, in the State of Quintana Roo, Mexico. The geographical coordinates of Coba Group (main entrance for tourist area of the archaeological site) are North 19° 29.6’ and West 87° 43.7’. The archaeological zone is reached by a two-kilometer branch from the asphalt road connecting Tulum with Nuevo Xcán (a community of Lázaro Cárdenas, another municipality of Quintana Roo) on the Valladolid to Cancún highway. Coba is located around two lagoons, Lake Coba and Lake Macanxoc. A series of elevated stone and plaster roads radiate from the central site to various smaller sites near and far. These are known by the Maya term sacbe (plural sacbeob) or white road. Some of these causeways go east, and the longest runs over westward to the site of Yaxuna. The site contains a group of large temple pyramids known as the Nohoch Mul, the tallest of which, Ixmoja, is some in height. Ixmoja is among the tallest pyramids on the Yucatán peninsula, exceeded by Calakmul at . Coba was estimated to have had some 50,000 inhabitants (and possibly significantly more) at its peak of civilization, and the built up area extends over some 80 km2. The site was occupied by a sizable agricultural population by the first century. The bulk of Coba's major construction seems to have been made in the middle and late Classic period, about 500 to 900 AD, with most of the dated hieroglyphic inscriptions from the 7th century (see Mesoamerican Long Count calendar).
