Maya: Ancient Metropolis (2020)

The Mayan civilization has baffled historians for centuries with its unprecedented prowess in math, astronomy, and engineering. All that was left of the Maya seemed to be the ruins of giant pyramids, but the most recent discoveries from archaeological excavations reveal much more: lost citadels of Tikal, in the Guatemalan jungle; a sacred cenote, or rock-sided sinkhole, at Chichén Itzá, on the north Yucatán Peninsula; and an underground network of tunnels discovered at Teotihuacan, northeast of Mexico City.
