Kohunlich is a large archaeological site of the pre-Columbian Maya civilization, located on the Yucatán Peninsula in Mexico about 25 km east of the Rio Bec region, and about 65 km west of Chetumal on Highway 186, and 9 km south of the road. The Spanish name does not actually derive from Mayan but from the English Cohune Ridge where cohune palm grew. The site covers about 21 acres (85,000 m2), surrounded by dense sub-tropical rainforest, and it contains almost 200 mounds, that remain largely unexcavated. The city was elaborately planned and engineered, with raised platforms and pyramids, citadels, courtyards and plazas surrounded with palace platforms, all laid out to channel drainage into a system of cisterns and an enormous reservoir to collect rainwater. The site was settled by 200 BC, but most of the structures were built in the Early Classic period from about 250 to 600 AD. -- Wikipedia
