For millennia Stonehenge has been the centrepiece of Neolithic funerals, druid festivals and pagan ceremonies. Now the iconic monoliths find themselves at the centre of a battle over traffic and money — and the potential destruction of priceless artefacts. The British Government wants to plunge a 2-kilometre, $3 billion tunnel underneath the Stonehenge World Heritage site — which houses one of the planet’s most iconic prehistoric monuments. Just a stone’s throw from the monoliths is the busy A303 highway, a road which connects London with south-west England.
