A bit of background info - part of my email to Rob Harding at English Heritage dated 17 July 2007 -
Dear Mr Harding
...I am writing to you to register, in the strongest possible terms, my objection to English Heritage's plan to insert a 'time capsule' in Silbury Hill... Are you aware that such an action contravenes one the basic rules of conservation, a rule which states that nothing should either be added or removed from a structure or object unless that addition or removal is absolutely necessary for the purpose of its conservation and preservation?
...If contravening the above were not bad enough what sort of message do you think English Heritage is sending to the public? That while it is necessary to correct the mistakes of the past with regard to tunnelling and the leaving of foreign objects within the structure, it is now acceptable for English Heritage to make the same mistake by leaving a time capsule within this unique and ancient monument? ...if there is no intention of ever re-tunnelling Silbury Hill to retrieve the capsule (and we hope there certainly is not) what on earth is the point of leaving it there?
...I believe the children of Avebury school are involved in preparing some of the objects to be inserted into the time capsule; while it is commendable that the children are in some way involved with the future of the monument this is not the way to teach them about conservation and respect for our heritage. As adults, the children of Avebury school may again one day visit Silbury Hill; what lesson do we want to leave for them there? The lesson that we are at liberty to change and deposit whatever we want, wherever we want, or the lesson that we try to leave things as they were originally intended? Isn't that what English Heritage should stand for?
Reply from Rob Harding -
Yours sincerely,
Rob Harding.
When all is said and done however it's well to remember that the time capsule is only a small factor in the overall conservation and the respect that Silbury deserves - the structural integrity of the monument itself may be in danger and that is of primary concern. The questioning, of course, will continue.
Best.
