The Bluestone Quarries

Craig Rhos-y-felin, Preseli Hills, Pembrokeshire

Where Stonehenge's bluestones were cut, 150 miles from Salisbury Plain.

Archaeologists have shown that some of Stonehenge's smaller 'bluestones' were quarried from outcrops in the Preseli Hills, such as Craig Rhos-y-felin, around 5,000 years ago. Some believe the stones first stood in a circle in Wales, perhaps at Waun Mawn, before being moved.

The Ledger of Lost Artifacts and Civilizations

Not every mystery needs a lost continent. This book investigates fifty-nine real and often overlooked puzzles from the ancient and modern world: a temple older than farming itself, astonishing structures, out-of-place artifacts, and technologies lost to time. Each case is weighed honestly, with a clear ledger of the case for and against, so you can make up your own mind. Some cases collapse under scrutiny. Others remain genuinely unexplained. All of them are stranger than Atlantis.
