FIG. 119.—Reconstruction of the peribolos, with the tower of Babylon, the temple Esagila, the quay wall of Nabonidus, and the Euphrates bridge. The tower is shown incomplete. (B) Bridge. (ET) Etemenanki. ] Two doors in the north and ten elaborate gateways with an inner court and towered façade afforded access to the interior. The two eastern of these and the four at the south are placed at the end of deep recesses formed by the outer wall being carried back, thus forming roomy forecourts. The four southern gateways have the typical towered façade also on the side that faces inwards. The southern gate on the east side, which was the largest, is destroyed, but we can reconstruct it without difficulty. Very little remains of the south-east corner. Near the south-west corner a chambered wall projects to the north, and with the outer wall forms a long narrow court in which there were no other chambers than those formed in the wall. Apparently this narrow court extended as far as the northern gateway in the western wall, and here apparently it joined at right angles another wall which extended here in the same line as the northern front of the great building on the east side; of this wall, however, only the western end now exists. It skirted a northern area, in which the above-mentioned private houses lay. We have thus three divisions inside the peribolos: the northern court (NH on Fig. 114) with the small houses, the long narrow western court (WH), and the principal court (HH) which contained the zikurrat of Etemenanki (ET) and all the other monumental buildings (Fig. 119). Low down on the north, close to the zikurrat, there were ancient buildings orientated in an entirely different direction, and on the east front, also at a great depth, there lay a large ancient building (Ä), over which the main building of the peribolos was carried. Neither of these had anything to do with the sanctuary as such.
