Piedras Negras (Maya site)

Piedras Negras is a major Classic Maya archaeological site in Guatemala’s Petén Department located on the banks of the Usumacinta River. The site is known for its acropolis, carved stelae and inscriptions that document its dynastic history.

Visitors and researchers encounter monumental plazas, pyramidal structures and a ballcourt, together with finely carved stelae bearing calendrical and genealogical inscriptions. The city’s monuments and layout indicate its role as a political and ceremonial center during the Classic period.

Piedras Negras flourished principally during the Classic Maya era, approximately the 5th through 9th centuries AD, and maintained regional influence within the Usumacinta river system. Archaeological investigations in the 20th century, including work by Tatiana Proskouriakoff, helped decode its inscriptions and sequence of rulers.

The site is situated on the Guatemalan side of the Usumacinta River in Petén, within a lowland tropical forest environment and is accessed via roads from regional towns and river approaches.
