Excavations during the 1997-2001 seasons were carried out inside perimeter wall [250]. Here a partial plan of those excavations shows superimposed levels of Period 3C buildings, all mostly robbed of their baked brick walls. [Mud-bricks are hatched, baked bricks are either not-filled-in (1999 excavations) or light gray in color (2001 excavations).] [See also 86, 89 and 72.)
