Piedras Negras, Maya Biosphere Reserve

Piedras Negras is the modern name for a ruined city of the pre-Columbian Maya civilization located on the north bank of the Usumacinta River in the Petén department of northwestern Guatemala. Piedras Negras is one of the most powerful of the Usumacinta ancient Maya urban centers. Occupation at Piedras Negras is known from the Late Preclassic period onward, based on dates retrieved from epigraphic information found on multiple stelae and altars at the site. Piedras Negras is an archaeological site known for its large sculptural output when compared to other ancient Maya sites. The wealth of sculpture, in conjunction with the precise chronological information associated with the lives of elites of Piedras Negras, has allowed archaeologists to reconstruct the political history of the Piedras Negras polity and its geopolitical footprint.
