Archaeologists Find Ancient Maya City With a Modern Grid Layout

An ancient Mayan city followed a unique grid pattern, providing evidence of a powerful ruler, archaeologists have found.

The city, which contains flat-topped pyramids, is being excavated at Nixtun-Ch'ich' in Petén, Guatemala. It was in use between roughly 600 B.C. and 300 B.C., a time when the first cities were being constructed in the area. No other city from the Maya world was planned using this grid design, researchers say.
