Archaeologists search for information about how Stonehenge was built and what that can tell us about the people who built it.

Alice Roberts recounts a campaign of excavations led by archaeologist Mike Parker Pearson that between 2014 and 2018 uncovered two sites crucially connected with the construction of Stonehenge. The first discovery was the Welsh quarry where the bluestones of Stonehenge were broken out of the volcanic outcrop. The dating of the quarry led to the search for a second site where the stones were originally set up in a circle for 400 years before being transported to their current location at Stonehenge.—JM

Professor Alice Roberts follows a decade-long historical quest to reveal a hidden secret of the famous bluestones of Stonehenge. Using cutting-edge research, a dedicated team of archaeologists led by Prof Mike Parker Pearson have painstaking compiled the evidence to fill in a 400-year gap in our knowledge of the bluestones - and to show that the original stones of Britain's most iconic monument had a previous life.
