Nixtun-Chʼichʼ is an Itza Maya archaeological site in Petén Department, Guatemala. It has an urban grid with fairly well ordered streets and avenues dated to around 2500 years ago. This is one of the earliest urban grids in the Americas and likely emerged as the ancient Maya developed more complex forms of political organization. It was likely a means to regulate and perhaps dominate the inhabitants. Nevertheless, the grid system at Nixtun-Chʼichʼ did not catch on and is not seen in later Maya cities. Read more on Wikipedia
