Palenque was a Mayan city state powerhouse during 600-800 AD.
It's signature building is the Pyramid of Inscriptions, where the best
known king's tomb was found. The pyramid cannot be climbed.
A profile shows the classic view of this pyramid and other similar
Mayan structures built in over 2,000 independent city states that
combined to form the Mayan Empire.
Palenque's other famous structure is the Palace, built for use by
later kings. It's tower has become another Palenque landmark.
The Maya constructed an aqueduct for Palenque, which still
operates, showing how much water the city had. Below the
main buildings here is the Queen's Waterfall.
