A team of archaeologists has discovered a hidden Mayan city in Mexico, believed to be one of the largest in ancient Latin America. The city, named Valeriana, was found using Lidar technology and is estimated to have housed 30-50,000 people at its peak from 750 to 850 AD. With pyramids, sports fields, and causeways connecting districts and amphitheaters, Valeriana is a significant find that sheds light on the region's rich cultural heritage.
