Stonehenge Didn't Stand Alone, Excavations Show

Recent excavations of Salisbury Plain in southern England have revealed at least two other large stone formations close by the world-famous prehistoric monument.

One of the megalithic finds is a sandstone formation that marked a ritual burial mound; the other, a group of stones at the site of an ancient timber circle.

The new discoveries suggest that many similar monuments may have been erected in the shadow of Stonehenge, possibly forming part of a much larger complex, experts say.
