A decade-long archaeological quest reveals that the oldest stones of Stonehenge originally belonged to a much earlier sacred site: a stone circle built on a rugged, remote hillside in West Wales. Using the latest tools of geotechnology, a dedicated team of archaeologists led by Professor Mike Parker Pearson (University College London) painstakingly searched for the evidence that would fill in a 400-year gap in our knowledge of the site's bluestones. Secrets of the Dead reveals the original stones of Europe's most iconic Neolithic monument had a previous life before they were moved almost 155 miles from Wales to Salisbury Plain.
