About 900 meters from Stonehenge evidence of a supposed celebration (feasting rather than ritual oriented) site has been discovered. Scientists say the evidence is of remains of what was once a ring of massive timber posts (up to 3 meters in diameter) thought to be of the same era as Stonehenge. This with other findings would make Stonehenge a complex rather than an isolated structure. The scientists are using ground penetrating radar to search for other sites and artifacts in the vicinity. They will be investigating for approximately three more years. The earliest phases of the construction of Stonehenge are thought to have occurred about 3000 BC.
