I'm not sure what types and style of wall these were - I don't recall seeing that in the articles.
Like medieval European and ancient Greek towns, those forming the Amazonian urban landscape were surrounded by large walls. These were composed of earthworks, the remains of which have survived.

The people who once lived in the settlements are thought to have been wiped out by European colonists and the diseases they brought with them.
Roads and canals connected walled cities and villages. The communities were laid out around central plazas. Nearby, smaller settlements focused on agriculture and fish farming.
