Yaxha  is a Mesoamerican archaeological site in the northeast of the Petén Basin region, and a former ceremonial centre and city of the pre-Columbian Maya civilization. Yaxha was the third largest city in the region and experienced its maximum power during the Early Classic period (c. AD 250–600).The city was located on a ridge overlooking Lake Yaxha. The name of the city derives from the Mayan for “blue-green water”; it is a notable survival of a Classic period place-name into the modern day. The Yaxha kingdom is estimated to have covered an area of 237 square kilometres  and to have had a peak population of 42,000 in the Late Classic period of Mesoamerican chronology.
