Solstício Archaeological Park is located in the state of Amapá. Translated from Portuguese, its name means "Solstice." In the spring of 2006, scientists discovered a cromlech - a circle of stones (megalithic monument). It is 30 metres in diameter and the height of granite steles is about 4 metres. A similar observatory was discovered in French Guiana. Often the cromlech in Sulsticiu is often compared to other megalithic monuments found in Europe, Asia and North America. The Solstício Amonument has been called the "Amazonian Stonehenge." Near the cromlech, archaeologists, found the remains of pottery. After examining they concluded that the structure could date from around the 1st to the 15th century AD.
The blocks that make up the cromlech are set vertically, like identical circles on the top of the hill. 21 December, the day of the winter solstice and the shortest day in the northern hemisphere, the shadow of one of the sides disappears. This happens when the sun appears directly above it. It's the fact that the block is aligned according to the solstice is what led scientists to speculate about the astronomical purpose of the cromlech. The second hypothesis suggests that the cromlech they found is a temple. The priests, relying on the position of the stars, conducted rituals of a religious nature in it.
The excavations in the archaeological park of Solstício are systematic. At present, the fossils found can neither confirm nor deny the hypothesis of an observatory.
Nowadays, Solstício Archaeological Park is a very popular place among tourists and among amateur historians.
