Discover an ancient observatory in Brazil

Archaeologists from the Amapa Scientific and Technical Research Institute (IEPA) have discovered an ancient observatory at Calcoene, about 390km from Macapa, the capital of Amapa state, near the border with French Guiana.

They say the station is about 2,000 years old, and only a multicultural society can build such a station. The station was built on 127 granite blocks, each 3m tall, and regularly arranged into circles on a wide field.

Radio is used as an observatory, because the blocks are arranged to see the winter solstice. In December, sunlight shines through a hole in one of the rocks, to calculate agricultural activity and religious rituals. Archaeologists say that the observatory's secret is similar to the famous Stonehenge station, in Salisbury (England), with large blocks of stone arranged regularly, but the purpose has not been clarified.
