cobá, méxico

Cobá is a very extensive (and mostly unexcavated) ancient Maya site in the Yucatán jungle, and includes the Nohoch Mul: the tallest pyramid on the Yucatán peninsula, over 130 feet high.

The majority of construction is thought to date from 500-900 AD, although some construction and repairs continued at least through the 1300s, if not to the time the Spanish conquistadors arrived.
