"Stonehenge is undoubtedly a major ritual monument, which people may have traveled considerable distances to come to, but it isn't just standing there by itself," project leader Vincent Gaffney, an archaeologist at the University of Birmingham in the U.K., told Live Science. "It's part of a much more complex landscape with processional and ritual activities that go around it. That's very different from how this has been viewed before. The important point is Stonehenge is not alone. There was lots of other associated ritual activity going on around it."
