Palenque, also anciently known in the Itza Language as Lakamha, was a Maya city-state in southern Mexico that perished in the 8th century. The Palenque ruins date from ca. 226 BC to ca. 799 AD. After its decline, it was overgrown by the jungle of cedar, mahogany, and sapodilla trees, but has since been excavated and restored. It is located near the Usumacinta River in the Mexican state of Chiapas, about 130 km (81 mi) south of Ciudad del Carmen, 150 meters (490 ft) above sea level. It is adjacent to the modern town of Palenque, Chiapas. It averages a humid 26 °C (79 °F) with roughly 2,160 millimeters (85 in) of rain a year.
