[Cob] mud brick Citadel in Bam

[Amanda Peck]

There is that, it could well be part of what has happened.   And you can 
site your building so the hill won't come down on you.  Rounded walls with 
buttresses, per Minke, work about as well as round.  But he did say that the 
old style of building--really thick rammed earth--that had not been 
practiced in the area he was talking about for some time, seemed to take 
shock better than the thinner stuff, unless, of course, you went to really 
flexible construction--e.g. wattle and daub.

I have no television reception here, and I haven't seen any recent pictures 
from Bam.  What DID it look like?

I hate to say this... however.. it could be that the old surviving
buildings are on specific
locations that don't move as violently as other adjacent places. thus
they survive because of chance and good construction  but not just on
good construction.

Meanwhile other buildings are built where the past ones got destroyed
again and again.
such a concept isnot out of the loop.
Getting back to basics  round construction has to stand up much better
than rectangular.
