There is a cover over some special part, containing a (mostly reconstructed) wall of the citadel and a megaron. Here are pictures of the citadel wall. This reconstruction built with hand-made and fired mudbrick preserves the original mudbrick material, which is concealed inside this wall to its full height (appr. 4 m). A fire gave the original brick of the upper and outer part of the wall (text missing, presumably: its current colour) and this colour has been reproduced in the reconstruction.
