Road network



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.

 


In modern settlements,
dams are used to funnel fish into weirs


Each community had an identical road, always pointing north-east to south-west, which are connected to a central plaza.

The roads were always oriented this way in keeping with the mid-year summer solstice.

Evidence was found of dams and artificial ponds - thought to have been used for fish farming - as well as open areas and large compost heaps.

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.
