Stonehenge 'clears people's minds' says arch druid

People come to Stonehenge to "clear their minds" according to Terry Dobney, the Arch Druid of Avebury in Wiltshire.

He told the Today programme that the Nato summit should have been held at Stonehenge because "the acoustics are quite good".

This comes after US President Barack Obama paid a visit to the ancient site while his returning from the summit in Newport.
