Parque Arqueológico do Solstício
The Parque Arqueológico do Solstício (Solstice Archaeological Park) is an archaeological site located in Amapá state, in the north of Brazil, near the city of Calçoene. The site contains a megalithic stone circle, colloquially known as the Amazon Stonehenge.
The megalithic site consists of 127 blocks of granite, each up to 4 m (13 ft) tall, standing upright in a circle measuring over 30 m (98 ft) in diameter. It is located on a hilltop on the bank of the Rego Grande river.
After conducting radiocarbon testing and carrying out measurements during the winter solstice at the Rego Grande site, scholars in the field of archaeoastronomy determined that an indigenous culture arranged the megaliths into an astronomical observatory about 1,000 years ago, or five centuries before the European conquest of the Americas began.
Archaeologists theorize that the site, referred to in academic sources as AP-CA-18, was built by indigenous peoples for astronomical, ceremonial, or burial purposes and likely a combination. The function of this archaeoastronomical site is unknown, much like other sites such as Stonehenge, a much older site in Great Britain.
Evidence has been found near the Rego Grande site and all over the Amazon to suggest that the indigenous people of the region lived in complex societies that involved both agriculture and a close relationship with the natural environment around them.
