A Maya center in Chiapas, Mexico, which reached its height during the Late Classic, coming into power when Teotihuacán declined. There are inscribed monuments erected between 630-810 AD, after which the site was abandoned. The buildings have fine relief decoration modeled in stucco or carved on limestone panels and they are know for unusual features (pillar and lintel doorways, mansard roofing). A richly furnished tomb of the Classic period was found underneath the pyramid of the Temple of the Inscriptions, equally important to Tutankhamun's in Egypt (jade ornaments, a number of sacrificed retainers, and a massive, elaborately carved sarcophagus). A subterranean vaulted aqueduct joins the central palace complex, with its unique four-story tower, to the eastern terraces where the Temples of the Foliated Cross, the Cross, and the Sun are situated. Palenque was the westernmost of the great Classic Maya sites. Palenque was among the first major centers to suffer in the general Mayan collapse; it was abandoned in 810.
