This tufo wall appears to be in phase with multiple North-South walls (SU 5416, SU5417) in area F-South and the Area Urbana. Each features the same red tufo, which is easily distinguishable from the gray tufo in other places, like SU 5451. The rubble layer 5499 joins the gray in the threshold to this SU; this rubble must have been used to level the wall when it was reused beneath the threshold. While 5460 appears more or less in its original position, it may have been slightly re-arranged in this later phase, explaining the smaller blocks.
