New henge dig begins

You will have heard of Stonehenge - and probably Avebury. Perhaps the two most famous stone-age sites in Britain. But an archaeological dig is beginning at another - nearby.

And the circle is ten times bigger than Stonehenge.

There was an archaeological dig there five years ago. But now students are back for one of the biggest excavations in the country.
