[Cob] mud brick Citadel in Bam

[Raduazo at aol.com]

     Note that it was adobe that collapsed not cob. There is a big 
difference. Historically mud bricks are no better and sometimes worse than fired brick. 
Cob on the other hand fairs much better. I think there is a record of this 
someplace in the sculpted house handbook, but I am not sure where.
