Archaeologists in the Czech Republic have discovered a prehistoric structure they believe was a ritual center linked to the movements of the sun and moon. The center is around 6,500 years old — about 1,000 years older than Stonehenge.
The structure was discovered at Chleby in the Central Bohemian Region. Archaeologists found a circular enclosure consisting of a ditch that was about 750 feet (230 meters) in diameter and 8 feet (2.5 m) deep. Twelve entrances that led to the center of the enclosure were located in different spots around the ditch, the team said in an Aug. 18 statement.
