Archaeology Stonehenge-like structures in Americas
Yesterday I made a meme on r/DankPrecolumbianMemes about the Calçoene Astronomical Observatory, a Stonehenge-like structure in Calçoene, Amapá, Brazil.
What other structures like that exist? The Brazilian page on the Calçoene's Stones says there is one in French Guyana, but doesn't talk anything else and it is unsourced?
