Coba
Coba is an ancient Mayan city on the Yucatán Peninsula, located in the Mexican state of Quintana Roo. The site is the nexus of the largest network of stone causeways of the ancient Mayan world, and it contains many engraved and sculpted stelae that document ceremonial life and important events of the Late Classic Period (AD 600–900) of Mesoamerican civilization.
