Comalcalco, located in Tabasco, is the most westward city of the Mayan area. It is differentiated from other Mayan sites by its use of brick as a substitute for stone. Its highest development came at the same time as that of other large cities of the Classic period, including Palenque, with which it had close ties. It may have even been an outpost for military reasons from the high command at Palenque.
Comalcalco's ruins show three large ceremonial complexes. The Grand
Acropolis, the North Group, and the East Acropolis. Individual structures include the Palace, the site's biggest building, and temples located in the Grand Acropolis.
