Few years back I went to take some photos of Stonehenge for HA when, (can anyone remember it) we were going to have a tunnel built at great cost.
Parked on the verge by a field gate on the A303 and walked down to photograph at Stonehenge Bottom, the triangle of roads with Stonehenge centred in the middle. Traffic whizzed by, and you realise how destructive the roads were to a very fine view of the stones. If you wander over to the barrows behind the visitor centre, and look from there, you have this view of the stones over the VC and the carpark, filled with coaches etc and you really do understand the need to get rid of roads, visitor centre and carparks and move them elsewhere.
Its not only the need to get to the stones close up, but its the landscape that has to be emptied of modern day intrusion to understand the significance of Stonehenge....
