Calakmul is one of
the largest known Mayan sites, located in Campeche in the TierrasBajas jungles. It covers approximately 70 square
kilometers, and is estimated to have had a population of 50,000 in the height of
its power. The central urban core of Calakmul is
delineated on the north by a substantial wall, probably for defense of the most
important political structures and residences.
