What It Is: An ancient Amazonian geoglyph—a massive geometric earthwork built by pre-Columbian Indigenous civilizations between 1,000 and 2,000 years ago.

Visible Features: A clear square/diamond trench structure (100–150m wide) with surrounding outer enclosures, revealed due to historical deforestation in the area.

Significance: Archaeologists believe these sites served ceremonial or gathering purposes rather than residential ones. Their existence proves the Amazon was once home to large, complex societies capable of major landscape engineering long before European arrival.
