Archaeologists in Brazil found a stone structure dating back to pre European colonization in the Amazonian state of Amapa (Northern Brazil).

The discovery, which showed sophisticated astronomy knowledge will change the previous thought that the area had primitive societies before European colonization.

The 127 stones were evenly spaced and pinpointed the winter solstice which might have been used to determine crop cycles. The structure is thought to be around 2,000 years old while the British Stonehenge dates to between 3000 and 1600 BC.
