Yup, that (and VBB's comments above) makes sense. What, actually, is the thinking on why the lintels eventually did come down? Wanton destruction or natural causes (or both)?
Maybe the explanation for the weakness of the ring lies with the half-height upright and two missing lintels ? That could also explain why the Southern section is more disturbed than the rest...
