Re: Silbury's structural integrity

I don't think comparing the size of the voids with the size of the hill as a means to illustrate how small they are is valid.


Quite, this is something of a red herring. Even minor subsidence in a structure can result in major damage. A few cracks in the foundations of Durham Cathedral would be seen as minuscule compared to the total mass of the building - left unchecked they could well be enough to bring down half the structure.

Bearing in mind the inner mound was said to be the most precious and delicate and sensitive to water I wonder what effect a central collapse of a saturated 125 cubic metres has had upon it.


Absolutely, that is why it is being asked where current thinking places the point(s) of entry of water into the structure and what measures are being taken to counter the problem? Answers please English Heritage.
