Archaeologists found a local equivalent of Stonehenge in Brazil

Brasilia - A long-ago stone structure resembling Britain's Stonehenge has been discovered by archaeologists in Brazil. This was reported today on the BBC's website.
A group of 127 massive stone blocks, which were embedded in the ground on a hill in the state of Amapá in remote northern Brazil, according to experts, served as an observatory or a ceremonial site.
The structure, made up of regularly arranged upright stones, each weighing several tons, suggests a deep knowledge of astronomy. The stones appear to be arranged to help determine the winter solstice.
Scientists believe that the structure was created before the arrival of European colonizers, thus refuting previous views that there were no advanced societies in the Amazon region prior to colonization.
The exact date of the structure's creation is still unknown, but the pottery found at the site is estimated to be 2000 years old. The dating of Stonehenge is placed between 3000 and 1600 BC.
