Last year a study made an extraordinary and controversial claim: Stonehenge was basically a second-hand monument from Wales. It would have stood there hundreds of years before it was dismantled and transported to Salisbury Plain in Wiltshire.
The research indicates that two quarries in the Preseli Hills of Pembrokeshire, in southwest Wales, are the source of Stonehenge's bluestones.
Carbon dating revealed such stones were dug out at least 500 years before Stonehenge was built -- suggesting they were first used in a local monument that was later dismantled and dragged off to England.
"Stonehenge was a Welsh monument from its very beginning. If we can find the original monument in Wales from which it was built, we will finally be able to solve the mystery," Mike Parker Pearson, director of the project and professor of British later prehistory at University College London said.
Researchers have been using geophysical surveys, trial excavations and aerial photographic analysis to identify the ruins of a lost, dismantled monument. The results of such research promise to make the headlines this year.
"We think we have the most likely spot. We may find something big in 2016," Kate Welham, of Bournemouth University, said.
