Although I am probably going to be in a minority I still think it was the right thing to do. There is no question that it was only a matter of time before the circle was lost to the elements, be that one year, ten years or 100 years. What would be gained by that? Think how many other sites are long gone due to the elements - sites we know nothing about. At least this one has been preserved as a testiment to its builders. Who knows what future benefits and understanding may come from its preservation? Better in a museum than gone forever.
Time Team get a lot of stick about 'Seahenge' but it was nothing to do with them. They just made a programme about what was already happening. It would have been removed whether Time Team were present or not. I still think this was Time Team's best 'special' of the very many they made.
