Dur-Sharrukin ("Fortress of Sargon"; Arabic: ), present day Khorsabad, was the Assyrian capital in the time of Sargon II of Assyria. Khorsabad is a village in northern Iraq, 15 km northeast of Mosul. The great city was entirely built in the decade preceding 706 BC. After the unexpected death of Sargon in battle, the capital was shifted 20 km south to Nineveh.
Sargon II ruled from 722 to 705 BC. The demands for timber and other materials and craftsmen, who came from as far as coastal Phoenicia, are documented in contemporary Assyrian letters. The debts of construction workers were nullified in order to attract a sufficient labour force. The land in the environs of the town was taken under cultivation, and olive groves were planted to increase Assyria's deficient oil-production. The great city was entirely built in the decade preceding 706 BC, when the court moved to Dur-Sharrukin, although it was not completely finished yet. Sargon was killed during a battle in 705. After his unexpected death his son and successor Sennacherib abandoned the project, and relocated the capital with its administration to the city of Nineveh, 20 km south. The city was never completed and it was finally abandoned a century later when the Assyrian empire fell. 
On 8 March 2015 the Islamic State of Iraq and the Levant reportedly started the plunder and demolition of Dur-Sharrukin, according to the Kurdish official from Mosul Saeed Mamuzini. The Iraqi Tourism and Antiquities Ministry launched the related investigation on the same day.
The town was of rectangular layout and measured 1758.6 by 1635 metres. The enclosed area comprised 3 square kilometres, or 288 hectares. The length of the walls was 16280 Assyrian units, which according to Sargon himself corresponded to the numerical value of his name. The city walls were massive and 157 towers protected its sides. Seven gates entered the city from all directions. A walled terrace contained temples and the royal palace. The main temples were dedicated to the gods Nabu, Shamash and Sin, while Adad, Ningal and Ninurta had smaller shrines. A temple tower, ziggurat, was also constructed. The palace was adorned with sculptures and wall reliefs, and the gates were flanked with winged-bull shedu statues weighing up to 40 tons. Sargon supposedly lost at least one of these winged bulls in the river.
In addition to the great city, there was a royal hunting park and a garden that included "all the aromatic plants of Hatti and the fruit-trees of every mountain", a "record of power and conquest", as Robin Lane Fox has observed. Surviving correspondence mentions the moving of thousands of young fruit trees, quinces, almonds, apples and medlars.
"On the central canal of Sargon's garden stood a pillared pleasure-pavilion which looked up to a great topographic creation: a man-made Garden Mound. This Mound was planted with cedars and cypresses and was modelled after a foreign landscape, the Amanus mountains in north Syria, which had so amazed the Assyrian kings. In their flat palace-gardens they built a replica of what they had encountered."
Dur-Sharrukin is roughly a square with a border marked by a city wall 24 meters thick with a stone foundation pierced by seven massive gates. A mound in the northeast section marks the location of the palace of Sargon II. At the time of its construction, the village on the site was named Maganuba. 
The site was first noticed by the French Consul General at Mosul, Paul-Émile Botta in 1842. Botta believed, however, that Khorsabad was the site of biblical Nineveh. The site was excavated by Botta in 1842-44, joined in the later stages by artist Eugène Flandin. Victor Place resumed the excavations from 1852 to 1855.
A significant number of the items recovered by the French at Dur-Sharrukin were lost in two river shipping incidents. In 1853, Place attempted to move two 30-ton statues and other material to Paris from Khorsabad on a large boat and four rafts. All of the vessels except two of the rafts were scuttled by pirates. In 1855, Place and Jules Oppert attempted to transport the remaining finds from Dur-Sharrukin, as well as material from other sites being worked by the French, mainly Nimrud. Almost all of the collection, over 200 crates, was lost in the river. Surviving artifacts from this excavation were taken to the Louvre in Paris.
The site of Khorsabad was excavated 1928-1935 by American archaeologists from the Oriental Institute in Chicago. Work in the first season was led by Edward Chiera and concentrated on the palace area. A colossal bull estimated to weigh 40 tons was uncovered outside the throne room. It was found split into three large fragments. The torso alone weighed about 20 tons. This was shipped to Chicago. The preparation and shipment of the bull back to the Oriental Institute was incredibly arduous. The remaining seasons were led by Gordon Loud and Hamilton Darby. Their work examined one of the city gates, continued work at the palace, and excavated extensively at the palace's temple complex. Since Dur-Sharrukin was a single-period site that was evacuated in an orderly manner after the death of Sargon II, few individual objects were found. The primary discoveries from Khorsabad shed light on Assyrian art and architecture.
