How many of these wood studded walls survive today? Wouldn't the wood eventually rot, weakening and breaking down the structure of the wall over time? (or, conversely, did the stone and mortar preserve the wood by protecting it from the elements?)
I'm also curious, as I'm not running across any pictures at the moment (although I've found many beautiful marble arches and buildings that were *once* marble faced), were the iron clamps visible on the finished building?
