The Itza Maya, Ko'woj, and Yalain groups around what is now Guatamela were still around, but there were not very many of them. By 1520, they had built themselves back up again and started to build cities. The Itza had their capital at Tayasal (also known as Noh Petén), and people who study the Maya civlisation think what's left of this city is below the modern city of Flores, Guatemala on Lake Petén Itzá. The Ko'woj had their capital at Zacpeten. Some Mayan cultures were still living in the southern highlands.
