As we have followed the Arachtu wall from the Southern Citadel up to the peribolos, and as this is the first great gateway in this vicinity after the Ishtar Gate, this building must, I think, according to the inscription just referred to, be the Urash Gate. It is, therefore, a matter of indifference whether our building is the same that existed in Nebuchadnezzar’s time, or whether it is later and dates from Nabonidus, for in the latter case a gateway that bore the name of the Urash Gate existed previously and in much the same place if not on exactly the same spot. It is possible that the massive brickwork that lies immediately to the west of the land pier belonged to this earlier gateway. This consists of two projections, between which there is a stepped wall.
The excavations here are still incomplete.

THE WALL OF NABONIDUS
We have not yet followed the fortification wall connected with the gateway just described far to the south. The ruins here lie deep under the rubbish of the Amran mound, and are difficult to get at. On the north the excavations have laid open this wall as far as the village of Kweiresh.
The wall, which is 7.67 metres thick, with its cavalier towers stands on the river bank upon a massive projecting banquette like the older moat wall, the Arachtu wall, and the north wall of the Principal Citadel. This arrangement can thus be clearly recognised as a peculiarity of walls that lie on a water-channel. Towers, alternately broad and narrow, are placed at a distance of about 19 metres from each other. The broad ones are 7.3, the narrow ones 6.3 metres wide. In some of these towers there are fittings for double doors, from which a somewhat steep ramp leads down to the river. The walls are in very bad condition, and it is impossible to say whether there were similar doors in every tower, or, if not, at what length of interval. The pavement is .47 above zero. In the north, a short distance in front of the Southern Citadel, the wall for two mesopyrgia bends somewhat towards the west to unite by a tower with the Western Outworks (p. [144]). In this tower was the outflow of the eastern canal that flowed past the Southern Citadel. The bend is obviously contrived in order to include the Western Outworks of the Southern Citadel in the city area.
Not far from the north-western corner of the peribolos we made a cross-cut through the high mounds that cover the wall, and here we found also the Arachtu wall of Nabopolassar and Nebuchadnezzar. The cut has been continued for some length to the north on the other side of the depression caused by the river-bed, and there it yielded walls of burnt-brick buildings of considerable thickness, but the river wall that corresponds with that on the left bank we have not yet uncovered. This excavation is very far from complete. The wall is apparently the same that was called by Herodotus (i. 180) αἱμασιή, which joined on to the wings of the outer city wall, and which Ctesias (Diodorus, ii. 3) called κρηπίς.

THE ARACHTU WALLS AT THE PERIBOLOS OF ETEMENANKI
Immediately in front of the northern portion of the west front of the peribolos there lies the Arachtu wall of Nabopolassar, of which we saw the commencement in the north at the Southern Citadel. As soon as we began the cross-cut mentioned above, we came on a length of wall in which was an inscribed brick that explained its purpose. Later on in the farther reaches of the wall we found numerous bricks of the same kind in situ. The text is identical with that already quoted on page [138] et seq. The wall lies lower than the burnt-brick kisu of the peribolos wall at this point. The Arachtu wall, which stands in water, reaches up only to .33 metres below zero with its ruins, while the kisu of the peribolos extends down to 2.24 metres above zero. The upper level of the river banquette lies without any intermediate space in front of the Nebuchadnezzar wall, which is 6 metres thick, and is exactly at zero level. The Nabopolassar wall consists of unstamped 31–centimetre bricks, the facing wall of 33–centimetre bricks, with the Nebuchadnezzar stamp. The smooth front of both walls faces west, the back is left rough as it was built up against the bank behind.
Both walls extend as far as the northern corner of the peribolos. From there the Nabopolassar wall runs in a straight line northwards to a distance of about 20 metres from the Southern Citadel, where it breaks off in ruins. Its line runs approximately on the western boundary of the additional building, and must therefore originally have made a curve in order to join at its commencement with the Sargon wall. From the Nebuchadnezzar wall a branch turns off at a very sharp angle at the above-mentioned place, and runs exactly in the direction of the ancient moat wall. Another branch joins on here with a doubly-grooved expansion joint, and runs in the direction of the northern part of the Nabonidus wall. Thus there are parts of four walls close together here, all of which belong to four consecutive changes in direction. At the same place a culvert passes through each of the walls, which must have carried off the surface water that collected to the north of the peribolos. Somewhat farther to the north we came upon two descending stairways in the Nabopolassar wall, which were walled up in a second building period. They are similar to those in the gateways in the Nabonidus wall.
The three walls are so near together, and follow so closely in the same direction, that if we prefer to consider the Arachtu to be a canal of the Euphrates, it here lies so close to the Euphrates that its existence is very problematic. The Euphrates wall of Nabonidus has here obviously replaced the Arachtu wall of Nabopolassar, which further argues for the identity of the Euphrates and the Arachtu (see p. [140]). That the Nabonidus wall and the stone bridge are buildings on the Euphrates, no systematic investigator can doubt. Otherwise we must assume that besides the two buildings found by us there existed yet a second embankment wall of Nabonidus which lay on the Euphrates, and a second stone bridge that led over the Euphrates. Without wishing to anticipate further research, I am inclined to assume the Arachtu to be, not a canal nor an arm of the Euphrates, but a semicircular widening of the river (see Hommel, op. cit. p. 283, note 1, Arach) (moon, fem. Arachtu?), which possessed a special name, and for which the name Arachtu could be used as well as that of Euphrates, as in the case of the Binger Lock on the Rhine. Possibly it was the haven of Babylon.
