These are pics of the first temple we visited, known as the mask temple...it had many reconstruction phases, the Mayans were constantly changing these structures. The archaeologists uncovered masks all over the temple which had been covered by stone for protection, they archaeologists left only the one you see out and covered the others back up. The carvings are limestone and deteriorate quickly. The Mayans built everything equal so if you see it on one side it will be exactly the same on all sides.
Mask close up, he is about 7 ft high.
