Most impressive was the Shamash Gate, which has been thoroughly excavated by Tariq Madhloum on behalf of the Iraqi Department of Antiquities.It was found to have been approached across two moats and a watercourse by a series of bridges in which the arches were cut out of the natural conglomerate.It was then proved that more than four-fifths of this great accumulation is prehistoric.painted pottery of the subsequent Early Chalcolithic (Copper-Stone Age) phases, characteristic of the north, was succeeded by gray wares such as occur westward in the Jabal Sinjār.In the Nergal Gate two winged stone bulls, attributable to Sennacherib, have been reinstalled: a site museum has been erected adjacent to it by the Iraqi Department of Antiquities.
The Adad Gate contained many inscribed tiles, and what may prove to be the Sin Gate contained a corridor that led through an arched doorway into a ramp or stairwell giving access to the battlements.
At this time the total area of Nineveh comprised about 1,800 acres (700 hectares), and 15 great gates penetrated its walls.
An elaborate system of 18 canals brought water from the hills to Nineveh, and several sections of a magnificently constructed aqueduct erected by the same monarch were discovered at Jerwan, about 25 miles (40 km) distant. The “K” collection included more than 20,000 tablets or fragments of tablets and incorporated the ancient lore of Mesopotamia.
Since 1966 restoration has proceeded on the throne room of Sennacherib’s palace and some of the adjoining chambers.
All the entrances to the two main chambers were found flanked by winged bull colossi, and a series of orthostats not recorded by any of the 19th-century excavators has been recovered.
Extensive traces of ash, representing the sack of the city by Babylonians, From the ruins it has been established that the perimeter of the great Assyrian city wall was about 7.5 miles (12 km) long and in places up to 148 feet (45 metres) wide; there was also a great unfinished outer rampart, protected by a moat, and the Khawṣar River flowed through the centre of the city to join the Tigris on the western side of it.
