The Mayan city of Palenque is something no one should miss when visiting Mexico. It has been declared a World Heritage Site by UNESCO and is in the area of Chiapas, Mexico in the south. The buildings here have been around since the 7th century, so this fact alone is an incredible sight. The buildings are characterized by peculiar "peaks" crowning the tops. Since the city was abandoned by the Maya, it was quickly covered by jungle vegetation, and was not rediscovered until the eighteenth century. Since then, archaeologists have discovered up to 34 buildings, but it is believed that there are still more than 1,000 structures covered by the forest.
