Off of the highway between Palenque in Chiapas and Chetumal, at Mexico’s border with Belize, lies the Mayan ruins of Kohunlich. The entire site is really beautiful, well worth turning off of the highway to get to. The Temple of the Masks was built around the year 500 A.D. and is home to some really beautiful examples of Mayan art and architecture. The masks, or stucco reliefs, are about 5 to 6 feet tall and represent the ruling family of Kohunlich. They are all facing the setting sun.
