That new excavation project of Stonehenge we've occasionally linked articles on has produced what appears to be a definitive summary of their findings. According to the report, it would seem the place was a ceremonial burial ground for perhaps a single family for something like 30 generations. Then, about 3500 years ago, it was abandoned and eventually forgotten. To provide a different time fix for just how ancient this place is, consider that when this place was abandoned after five centuries of use, the pyramids were just being built. Even more tantalizing are remains that seem to indicate the site was in use more than 10,000 years ago.
