Palenque (Bàak' in Modern Maya) was a Maya city state in southern Mexico that flourished in the 7th century. The Palenque ruins date back to 226 BC to its fall around 1123 AD. After its decline it was absorbed into the jungle, which is made up of cedar, mahogany, and sapodilla trees, but has been excavated and restored and is now a famous archaeological site attracting thousands of visitors. It is located near the Usumacinta River in the Mexican state of Chiapas, located about 130 km (81 mi) south of Ciudad del Carmen[citation needed] about 150 m (164 yd) above sea level. It stays at a humid 26°C (79°F) with roughly 2160 mm (85 in) of rain a year.
