Plan view of the east side of Mound E and the west side of Mound ET showing areas excavated between 1993 and 2001 (Trenches 9, 10, 11). The massive perimeter wall of Mound E encloses architectural remains of Harappa phase Periods 3B and 3C and probably also of Periods 3A and 2, although those were reached only in a sounding in Trench 11 outside (to the East) of wall [250]. "Ring roads" ran both inside and outside of the perimeter wall. Trash and building debris were discarded into those roads, causing both faces of the wall to become progressively buried through time.
