Calakmul (/ˌkɑːlɑːkˈmuːl/; also Kalakmul and other less frequent variants) is a Maya archaeological site in the Mexican state of Campeche, deep in the jungles of the greater Petén Basin region. It is 35 kilometres (22 mi) from the Guatemalan border. Calakmul was one of the largest and most powerful ancient cities ever uncovered in the Maya lowlands. Throughout the Classic Period, Calakmul maintained an intense rivalry with the major city of Tikal to the south, and the political maneuverings of these two cities have been likened to a struggle between two Maya superpowers.
