This wall is the western wall of Room H13, which seems to have been only fully enclosed on the western side and the western part of the southern side (by wall 7284) in a relatively late phase. Previously, at least part of the space to the east (bounded by wall 7078) may have been open to the basalt-paved piazza like the area immediately to the north seems always to have been.
