This wall belongs to the later, imperial reorganization of the original long space between ashlar walls 7078/7073 and 7108. Together with wall 7115 and threshold 7185, this wall formed the limit between Rooms 4 and 5. It cannot be determined at the moment whether the two squared tufo blocks on which the concrete elevation of the wall was founded are in situ from an earlier phase, or were spoliated from elsewhere; either way they are almost certainly reused/repurposed.
