Archaeologists carrying out an excavation at Stonehenge say they have
broken through to a layer that may finally explain why the site was
built.
The team has reached sockets that once held bluestones - smaller stones,
most now missing or uprooted, which formed the site's original
structure.
The researchers believe that the bluestones could reveal that Stonehenge
was once a place of healing.
The dig is the first to take place at Stonehenge for more than 40 years.
The team now needs to extract organic material from these holes to date
when the stones first arrived.
