Archaeologists have known for many years that Mayan civilization was sophisticated, but this new discovery that they built on a grid is exciting. They designed at least some of their cities to have standardized “blocks.” Is there a social significance to each block? Did they have a block for potters and weavers? A block where Traders set up their wares? A block where the elite lived? For metal workers? Well, more work needs to be done, but we suspect they did. Like any city planner, Mayan planners probably included utility and status into their designs.
