It should have been left where it was and protected by a cofferdam as is done in Denmark and elsewhere. The structure and location were all important and now all that we have are lumps of wood. I was there just before the extraction and spoke to many people including the squatting druids. Local peole said that they had known about it for years as it was periodically uncovered and covered again. They were certain that it was in no danger from the sea - it had lasted 3000 years so why not longer!
The archaeos really made me angry as did Francis and Maisie Pryor. The obtaining and study of core samples, tool marks and micro-fossils were given as the reason for demolition - all could have been obtained while the monument remained in situ. Just imagine if Stonehenge was demolished to prevent erosion and to enable the archaeos to study the stones better. Sheer arrogant vandalism based on the assumption that heritage belongs to the academics and not to the people.
