The Atatürk Dam ( Turkish : Atatürk Barajı ), originally the Karababa Dam , is the third largest dam in the world and it is a zoned rock-fill dam with a central core on the Euphrates River on the border of Adıyaman Province and Şanlıurfa Province in the Southeastern Anatolia Region of Turkey . Built both to generate electricity and to irrigate the plains in the region, it was renamed in honour of Mustafa Kemal Atatürk (1881–1938), the founder of the Turkish Republic . The construction began in 1983 and was completed in 1990. The dam and the hydroelectric power plant , which went into service after the upfilling of the reservoir was completed in 1992, are operated by the State Hydraulic Works (DSİ) . The reservoir created behind the dam, called Atatürk Reservoir ( Turkish : Atatürk Baraj Gölü ), is the third largest in Turkey.

218-520: A battle against the Turks in the year prior, motivating the abandonment, whereas another states that the Mongols themselves caused the damage during the abandonment. The Mongols are also variously stated to either have simply walled up the gates but otherwise left what remained intact or to have pillaged the city for building materials before burning down the remnants. One major reason for the abandonment

Harran's possibilities for development are subject to several limiting factors, including

872-756: A provincial capital often second in importance only to the Assyrian capital of Assur itself. During the collapse of the Assyrian Empire, Harran briefly served as the final capital of the Neo-Assyrian Empire (612–609 BC). The city continued to be prominent after the fall of Assyria and experienced varying degrees of foreign cultural influence during its time under the Neo-Babylonian (609–539 BC), Achaemenid (539–330 BC), Macedonian (330–312 BC) and Seleucid (312–132 BC) empires. During classical antiquity Harran

1090-488: A third. Syria and Iraq claim to be suffering severe water shortages due to the GAP development. Both countries allege that Turkey is intentionally withholding supplies from its downstream neighbors, turning water into a weapon. Turkey denies these claims, and insists it has always supplied its southern neighbors with the promised minimum of 500 m/s (18,000 cu ft/s). It argues that Iraq and Syria in fact benefit from

Later sources indicate that the deities worshipped by the pagans of Harran in late antiquity included Sin, Bat-Nikkal (consort of Sin;

1744-460: Is expected to in the future once more transform Harran into an important local center. Economic issues caused by the Syrian civil war across the nearby Syrian border has recently caused many Harranian families to migrate elsewhere for work, such as to the cities Urfa (ancient Edessa), Adıyaman and Gaziantep . The Harran Castle is a large brick fortress of unknown date, though ancient Greek inscriptions found at one of its gates suggest that it

1853-462: Is higher up the water table than Harran and as more wells were constructed in Edessa, those in Harran gradually dried up. Harran was in the 12th century still renowned for its ancient origins; a now lost work by Hammad al-Harrani made the claim that Harran had been the first city founded after the great flood . Despite the threat of water scarcity , Harran continued to be an important town under

1962-431: Is its ancient burial mound , spread over a large area and partially surviving intact at the center of the city's archaeological site. The burial mound preserves inscriptions and architectural elements from several different cultures and appears to have been in continuous use from the 3rd century BC to the 13th century AD.

2180-534: Is not seen elsewhere in Turkey and is rare in the rest of the world. Houses similar to the modern beehive houses have long been present in Harran; the earliest known buildings from Harran appear to have been circular and Assyrian reliefs from the 7th century BC depict domed buildings architecturally similar to the present beehive houses. They have not been consistently present on the site, instead being built, ruined, forgotten and rebuilt multiple times throughout Harran's history. Beehive houses were recorded at Harran by

2289-490: Is noted that the walls of Harran were in poor condition. This issue was not rectified until repairs conducted in the reign of Justinian I ( r.  527–565 ). From the time of the Christianization of Mesopotamia and Syria until long into the Middle Ages, Harran developed a rivalry with the nearby city of Edessa due to the cities having polarised attitudes concerning Christianity.

2834-504: The 1270s. The Mamluks repaired the castle at some point, most likely in the 1330s or 1340s, and it became the seat of a local military governor, but there was otherwise little effort spent on trying to revive the city. By this point Harran was no longer on any of the major trade routes. A small village-sized settlement sprung up at the site, probably in the immediate vicinity of the castle. The space within Harran's city walls gradually filled up with dirt and sand through natural means. Over

2943-527: The 12th century, Harran at times fell under the influence of the County of Edessa , a short-lived crusader state . There is no record of the crusaders ever conquering Harran but the Harran Castle preserves remnants of a Christian chapel with distinct crusader architecture, perhaps suggesting a peaceful crusader presence. The growth of Edessa under Christian rule contributed to the decline of Harran. Edessa

The dam embankment is 169 m high (554 ft) and 1,820 m long (5,970 ft). The hydroelectric power plant (HEPP) has a total installed power capacity of 2,400 MW and generates 8,900 GW·h electricity annually. The total cost of

3379-465: The Euphrates entirely for a month to begin filling up the reservoir. Turkey had notified Syria and Iraq by November 1989 of her decision to fill the reservoir over a period of one month explaining the technical reasons and providing a detailed program for making up for the losses.

3706-592: The Islamic period. The city retained a highly heterogenous population that practiced many different religions. Some adopted syncretistic faiths tolerable by the Muslims, others continued to honor the old deities of ancient Mesopotamia and Syria, and some primarily worshipped the stars and planets. The Harranian pagans considered themselves the heirs of ancient star-worshipping civilizations such as Babylonia, Greece, India, Persia and Egypt. In addition to pagans, Harran

3815-739: The Islamic period. It flourished as a center of science and learning and was the site of both the first Islamic university (the Harran University ) and the oldest mosque in Anatolia (the Harran Grand Mosque  [ tr ] ).

3924-614: The Karkamış Dams downstream the Atatürk Dam are constructed for the purpose of harnessing the waters released from large-scale dams and HEPPs. Nearly 4,760 km (1,840 sq mi) of arable land in the Şanlıurfa - Harran and Mardin - Ceylanpınar plains in upper Mesopotamia is being irrigated via gravity-flow with water diverted from the Atatürk Dam through the Şanlıurfa Tunnels system, which consists of two parallel tunnels, each 26.4 km (16.4 mi) long and 7.62 m (25.0 ft) in diameter. The flow rate of water through

4142-532: The Umayyads. The move of the capital to Harran caused some outrage; the Banu Kalb tribe saw it as an abandonment of Syria and under Yazid ibn Khalid al-Qasri besieged the former capital of Damascus before being suppressed. Harran did not continue to function as a capital under the succeeding Abbasid Caliphate , though the city enjoyed some special privileges. When Al-Mansur ( r.  754–775 ) ordered

4251-414: The amount of productive land and the relatively limited area reserved for urban development. In his seyahatnâme from the 17th century, Evliya Çelebi mentioned that the vicinity of Harran was inhabited by Bedouins of Qays and Mawali tribes. The local culture is predominantly Arabic in terms of lifestyle, clothing and food. Harran has close social, cultural, commercial and urban relations with Urfa,

4360-411: The ancient ruins since the 1950s, newer houses constructed in Harran are mostly concrete structures with no architectural relation to the beehive houses. Concrete houses have been built both alongside beehive houses and outside the ancient city walls. The majority of the population of Harran today live in a more newly constructed village about 2 kilometres (1.2 miles) from the old city center. Harran

4469-419: The ancient walls they only produced brackish water and were thus only useful for providing water to animals. The water at Harran had perhaps been contaminated from seeping saltpeter from its ancient ruins.

4687-732: The biggest of a series of 19 power plants of the GAP project. It consists of eight Francis turbine and generator groups of 300 MW each, supplied by Sulzer Escher Wyss and ABB Asea Brown Boveri respectively. The up to 7.25-metre-diameter (23.8 ft) steel pressure pipes (penstocks) with a total weight of 26.600 tons were supplied and installed by the German NOELL company (today DSD NOELL ). The power plant's first two power units came on line in 1992 and it became fully operational in December 1993. The HEPP can generate 8,900 GWh of electricity annually. Its capacity makes up around one third of

The earliest written records concerning Harran suggest that

5014-435: The caliphate (including Alexandria ) and installing them in Harran. Harran was made the capital of the Umayyad Caliphate under its last caliph, Marwan II , from 744 to 750. The reason for Marwan moving his court to Harran is not known, but might be either to better monitor the troublesome eastern provinces of the caliphate or due to the anti-Christian sentiment of the city's pagan population, who had never been disloyal to

5123-434: The capital of Assur itself. In the 10th century, Harran was one of the few cities, along with Assur, to be exempt from needing to pay tribute to the Assyrian king and in the 9th and 8th centuries BC, Harran was made the seat of the turtanu , the Assyrian commander-in-chief. Since Harran was the sacred city of the moon-god, many Mesopotamian kings travelled there to receive the blessing and confirmation of their rule from

The demolished Harran University

5341-485: The city from paying the tribute he demanded from Edessa on account of Harran not being Christian like his enemies but rather a stronghold of the "old religion". The endurance of paganism at Harran in the Christian late Roman Empire is likely only explainable through the pagans there offering regular bribes to church officials and civil administrators in the region. In 590, Emperor Maurice ( r.  582–602 ) ordered

5559-521: The city itself was founded c. 2500 –2000 BC as a merchant outpost by traders from the Sumerian city of Ur . Harran was from early on associated with the Mesopotamian moon-god Nanna (later known as Sin) and soon became regarded as a sacred city of the moon.

The Ekhulkhul was renovated twice in the Neo-Assyrian period by the kings Shalmaneser III ( r.  859–824 BC) and Ashurbanipal ( r.  669–631  BC). Prophecies made by prophets and oracles of the moon cult of Harran were held in high regard; in the 670s BC the Harranians correctly prophesied that Esarhaddon ( r.  681–669  BC) would conquer Egypt and Sasi ,

The Atatürk Reservoir , extending over an area of 817 km (315 sq mi) with a water volume of 48.7 km (63,400 million cu yd), ranks third in size in Turkey after Lake Van and Lake Tuz . The reservoir water level touched 535 m (1,755 ft) amsl in 1994. Since then, it varies between 526 and 537 m amsl. The full reservoir level

6540-443: The course of its early history, Harran rapidly grew into a major Mesopotamian cultural, commercial and religious center. It was made a religiously and politically influential city through its association with the moon-god Sin ; many prominent Mesopotamian rulers consulted with and renovated the moon-temple of Ekhulkhul in Harran. Harran came under Assyrian rule under Adad-nirari I ( r.  1305–1274  BC) and became

The initial development project for the southeastern region of Turkey was presented in 1970. As the objectives for regional development have changed significantly and the ambitions have grown in the 1970s, the original plan underwent major modifications. The most important change in

There are 136 neighbourhoods in Harran District: In its most prosperous periods in ancient and medieval history Harran was probably home to around 10,000–20,000 residents. As a result of Harran's retransition into a permanent settlement over the course of the late 20th century and early 21st century, the city and surrounding district has experienced a rapid population increase. Despite this, Harran retains predominantly rural characteristics. As of 2022, Harran had

6867-463: The destruction of the walls of all cities in northern Mesopotamia, Harran was a notable exception. The Harran University underwent its golden age in the 8th century, particularly under the Abbasid caliph Harun al-Rashid ( r.  786–809 ).

7085-604: The increasingly Christianised late Roman Empire. As late as the early 5th century, the theologian Theodoret wrote that Harran was "a barbarous place, full of the thorns of paganism". At the Second Council of Ephesus (449), the Bishop of Harran , Stephen, was accused of accepting bribes from pagans to let them practice their rituals in peace. Harran was briefly captured by the Sasanian king Khosrow I in 549, who exempted

7194-408: The last moon temples were closed and destroyed. The precise date when this happened and the events surrounding it are unknown, perhaps coinciding with the city falling under the control of the Fatimid Caliphate in 1038 through the submission of the Numayrid ruler Shabīb ibn Waththāb , or more likely with a failed anti-Uqaylid rebellion in 1083. Izz al-Din ibn Shaddad reported that a Sabian temple

7303-415: The late 10th century. The power of the Abbasid Caliphate and its vassals in the region around Harran (the Hamdanid dynasty ) declined at the end of the 10th century. A new local Arab dynasty emerged during this time, the Numayrid dynasty , who ruled a small realm with Harran as its capital from 990 to 1081. The toleration of paganism at Harran was at last revoked for the final time in the 11th century and

7412-534: The many cultures that have inhabited Harran constructed them is not known. The walls were most likely constructed under either Roman or Byzantine rule. Inscriptions in both Greek and Syriac have been discovered during excavations of parts of the walls. The walls of Harran resemble those of the nearby Edessa, though are slightly smaller. They are vaguely elliptical in layout, normally around 3 metres (9.8 feet) thick and approximately 4.5 kilometres (2.8 miles) long and 5 metres (16 feet) high. Before they fell into ruin,

7521-449: The middle of the 20th century, Harran comprised about a hundred houses, inhabited by semi-settled nomadic Arabs, most of whom still did not stay at the site for the duration of the entire year. The city's ancient water systems had long fallen into disrepair and Harran in the 20th century had only a single source of drinking water, Jacob's Well, about 1.6 kilometres (0.99 miles) west of its walls. Although six wells were still operational within

7630-429: The mountains of eastern Anatolia and flowing southwards to Syria and Iraq , the Euphrates and the Tigris are very irregular rivers, used to cause great problems each year with droughts in summer and flooding in winter. The water of the Euphrates River is regulated by means of large reservoirs of the Keban and Atatürk Dams. However, the waters released from the HEPPs of those dams also need to be regulated. The Birecik and

7739-400: The nature of the earlier protocol by forming a joint committee on technical issues, which Syria joined later in 1982 as well. Turkey unilaterally guaranteed to allow 15.75 km/year (500 m/s) of water across the border to Syria without any formal agreement on the sharing of the Euphrates water. Mid-January 1990, when the first phase of the dam was completed, Turkey held back the flow of

7848-414: The new religion very early, Harran remained a pagan stronghold for centuries and became the largest center of pagan cults in eastern Syria. Harran was still overwhelmingly pagan in the 4th century, to the degree that the bishop appointed to Harran in 361 refused to reside in the city and instead lived in Edessa. Despite its paganism, Harran was a site of interest to Christians since the city is mentioned in

7957-465: The newly established Neo-Babylonian Empire and the Medes . The Assyrian capital of Nineveh fell in 612 BC but the remnants of the Assyrian army, led by Crown Prince Aššur-uballiṭ II , rallied at Harran. Harran is therefore typically regarded as the short-lived final capital of ancient Assyria. Aššur-uballiṭ II underwent a coronation ceremony at Harran, being invested with rulership by Sin. After

8066-466: The nomadic lifestyle of the locals since they can be built and dismantled rapidly, like a tent, but also efficiently resist both heat and cold. Because of the weak materials used for plastering the beehive houses require repair every 1–3 years. Their walls are usually 50–60 centimetres thick and their domes are about 20–30 centimetres thick. The domes have an opening at the top which provides natural air circulation and ventilation. This feature, combined with

8175-615: The oldest extant buildings in Harran is a beehive complex that today serves as the Harran Culture House ( Harran Kültür Evi ), a local museum and restaurant. The Culture House building was originally built c. 1800 but fell into ruins at some point and was rebuilt for tourism purposes in 1999. The museum showcases artefacts as well as traditional jewelry and clothes from the region surrounding Harran. Since prohibitions relating to conservation of historical monuments has hindered locals from gathering building materials from

8284-467: The present conical domes are built on larger cubical bases. Since wood is rare in the region around Harran owing to its climate, locals have traditionally built houses from materials they could easily gather such as stone, brick and mud. The modern beehive houses were constructed by locals who learnt how to build them by examining excavated ancient buildings and used bricks gathered from the ruins as building material. The beehive houses were compatible with

8393-556: The project was abandoning the Middle Karababa Dam design, and adopting the design of the Atatürk Dam to increase the storage and power generation capacities of the dam. Dolsar Engineering and ATA Construction, two prominent Turkish companies, signed for the building of the dam. The construction of the cofferdam began in 1985 and was completed in 1987. The fill work for the main dam lasted from 1987 to 1990. The Atatürk Dam, listed in international construction publications as

8502-536: The regulated water by the dams as they protect all three riparian countries from seasonal droughts and floods. Two damaging earthquakes of M w 5.5 and M w 5.1 occurred in the town of Samsat near the Atatürk Reservoir in 2017 and 2018, respectively. The spatio-temporal evolution of seismicity and its source properties in relation to the temporal water-level variations and the stresses resulting from surface loading and pore-pressure diffusion shows

8611-502: The remaining part is added in Syria , but nothing is contributed further downstream in Iraq. In general, the stream varies greatly in its flow from season to season and year to year. As an example, the annual flow at the border with Syria ranged from 15.3 km (3.7 cu mi) in 1961 to 42.7 km (10.2 cu mi) in 1963. One of the most important legal texts on the waters of

8720-418: The ruins of the mosque. As a result, the mosque enjoys more scholarly support as the most likely site of the ancient temple. The old town of Harran is still largely surrounded by Harran's ancient city walls. Though they are in generally poor condition, some stretches are well-preserved in good condition and give an idea of how the settlement once looked. The exact date of the current walls and which of

8829-554: The rule of the Ayyubid Sultanate , which followed the Zengids. Saladin ( r.  1174–1193 ) at some point enlarged Harran's Grand Mosque  [ tr ] and thereafter granted Harran to his brother Al-Adil I (later sultan 1200–1218). Al-Adil later gave Harran to his son Al-Kamil (later sultan 1218–1238). Harran was then under the rule of Al-Kamil's brother Al-Ashraf Musa 1202–1228/1229, after whose death

8938-599: The scholar Thābit ibn Qurra in the late 9th century, who could have learnt Neoplatonism in Baghdad. Alternatively, Neoplatonism might have been brought to Harran as early as the 6th century by Neoplatonists such as Simplicius of Cilicia , who fled persecution in the Byzantine Empire. The local Harranian religion continued to develop as a blend of ancient Mesopotamian religion and Neoplatonism and Harran remained notorious for its strong pagan traditions long into

9047-412: The site. The precise location of the ancient great Ekhulkhul temple is unknown and no certain archaeological evidence of it has yet been found. It is likely that one of the major medieval buildings of Harran displaced the Elkhulkhul and were constructed on top of it, either the Harran Castle or the Grand Mosque. Writings from the Islamic period contradictingly claim that the castle or the mosque were

9156-400: The start of the detailed geodetic monitoring in 1992. The maximum horizontal (radial) deformation measured is about 2.9 m (9.5 ft). The permeation grouting work was carried out by subcontractor Solétanche Bachy and the rehabilitation work for the post-tensioning of the dam crest with ground anchors by Vorspann System Losinger International (VSL). The HEPP of the Atatürk Dam is

9265-403: The temple of Sin. Harran, along with the nearby cities of Nisibis and Hatra , were captured by the Sasanian king Ardashir I in 238–240 but was swiftly retaken by Emperor Gordian III . Later in 296, Harran was also the site of a battle where the future emperor Galerius suffered a crushing defeat against the Sasanian king Narseh . In the writings of Ammianus Marcellinus (359), it

9374-427: The thick walls, provide relatively good indoor conditions throughout the year, even in the extreme summer heat. As of a count conducted in 2002, Harran had 2,760 beehive houses though the number in the old town has since declined to a few dozen. Some of the beehive houses remained inhabited until the 1980s but they are today mainly used as store houses and barns and have been under conservation since 1979. One of

9483-467: The time the city was his capital. The masonry of the mosque indicates that it was restored several times throughout its history. Measuring 104 by 107 metres (341 ft × 351 ft) at its height, the mosque has fallen into ruin over the centuries and little of it remains standing today. Remaining portions include the eastern wall, the mihrab , a fountain, and the 33.3-metre (109-foot) tall minaret . Another important historical monument in Harran

9592-470: The total capacity of the GAP project. During the periods of low demand for electricity, only one of the eight units of the HEPP is in operation while in times of high demand, all the eight units are in operation. Hence, depending upon the energy demand and the state of the interconnected system, the amount of water to be released from the HEPP might vary between 200 and 2,000 m/s in one day. Originating in

9701-410: The tunnels is about 328 m/s (11,600 cu ft/s), which makes one-third of the total flow of the Euphrates. The tunnels are the largest in the world, in terms of length and flow rate, built for irrigation purposes. The first tunnel was completed in 1995 and the other in 1996. The reservoir behind the dam will irrigate another 406,000 ha by pumping for a total of 882,000 ha. The Atatürk Dam and

9810-480: The walls had 187 bastions and 6–8 gates, most of which are in ruined condition today. Only one of the medieval gates of Harran, the Aleppo Gate, remain standing today. The walls were once surrounded by a great moat filled with water. Harran mainly attracts attention today due to the distinctive vernacular architecture of the houses in its old town, known as beehive houses ( kümbets ). This building type

9919-456: The water-level and seismicity rate are anti-correlated in this dam, which is explained by the stabilization effect of the gravitational induced stress imposed by water loading on the local faults. The overall effective stress in the seismogenic zone increased over decades due to pore-pressure diffusion, explaining the enhanced background seismicity during recent years. Bozova Bozova ( Ottoman Turkish : بوزاووه Kurdish : Hewenge )

10028-450: The world's largest construction site, was completed in a world record time of around 50 months. The rock-fill dam undergoes deformations that are regularly and systematically monitored since 1990 with different types of sensors. It is estimated that the central portion of the dam crest has settled by around 7 m (23 ft) since the end of the construction. Settlement of the dam crest up to 4.3 m (14 ft) has been measured since

10137-465: The worst military defeats in Roman history. Osroene (and thus also Harran) first came under Roman control as a result of the wars of Lucius Verus and Avidius Cassius in 162–166 AD. Harran gained colonial status under Emperor Septimius Severus in 195. Sources from Roman times describe Harran as a fortified garrison town. In 217, the Roman emperor Caracalla was murdered in Harran while visiting

10246-527: The Şanlıurfa Tunnel system are two major components of the GAP project. Irrigation started in the Harran Plain in the spring of 1995. The impact of the irrigation on the economy of the region is significant. In ninety percent of the irrigated area, cotton is planted. Irrigation expansion within the Harran plains also increased Southeastern Anatolia's cotton production from 164,000 to 400,000 metric tons in 2001, or nearly sixty percent. With almost 50% share of

10355-456: Was a Turkish district until 1946, after when it was downgraded to a sub-district of the Akçakale district. It regained its status as a district in 1987. Today, it is a major local tourist spot. The town is particularly famous for its unique beehive houses , which are reminiscent of buildings that were already present at Harran in ancient Mesopotamian times. The name Harran is recorded for

10464-475: Was a major deity in Ur, which also housed his main temple, but Harran's devotion to the moon can perhaps also be explained by its geography and climate. According to Donald Frew, the sun was a natural enemy in the hot and desolate landscape surrounding Harran whereas the night (and thus the moon) were more comforting. The sun-god Shamash is however also thought to have had a temple in Harran. Another prominent deity in

10573-475: Was also an important site for translations of documents from Syriac and Greek into Arabic and Harran flourished as a center of science and learning. Al-Rashid furthermore supplied Harran with a new water supply, constructing a canal from the Balikh River . At some point, Neoplatonism was introduced to Harranian intellectuals, though the precise timing is not clear. It might have been brought to Harran by

10682-400: Was also home to Muslims, Christians, Jews, Samaritans , Zoroastrians , Manicheans , and other groups. In 830, Harun al-Rashid's son Al-Ma'mun ( r.  813–833 ) arrived at Harran with an army on his way to raid in the Byzantine Empire and intended to destroy the city due to its large pagan population. Al-Ma'mun asked the populace if they were Muslims, Christians or Jews (" people of

10791-460: Was also important due to its strategic placement on an intersection of trade routes. Because Harran had an abundance of goods that passed through its region, it often became a target for raids. In the 19th century BC, the lands surrounding Harran were occupied by confederations of semi-nomadic tribes. In the following century the Amorite king Shamshi-Adad I ( r.  1808–1776  BC)

10900-473: Was conquered by the Mongol Empire in 1260 but was largely destroyed and left abandoned in 1271. Although Harran was kept as a military outpost under some later regimes, it has over the last five centuries mainly been used as a temporary settlement by local nomadic societies. Harran transitioned back into a semi-permanent village settlement in the 1840s, but has only recently grown into a permanent town through advancements in local irrigation and agriculture. Harran

11009-670: Was destroyed by the Uqaylid dynasty governor Yahya ibn as-Shatir, who conquered Harran in 1081. In 1059, the Harran Castle , presumably constructed in Byzantine times, was rebuilt and strengthened by the Numayrid ruler Manīʿ ibn Shabīb . By the 1180s, Harran was fully devoted to Islam with little to no traces of its former moon cult. In the late 11th and early 12th century, political control in northern Mesopotamia and Syria

11118-428: Was founded at some point during Byzantine rule (4th–7th centuries). It is also possible that it was built under Muslim rule in the 9th century. If it was not built in the 9th century, it is likely to at least have been expanded in the early Islamic period. Before its fall into ruin, the castle was a three-story structure. It was probably initially a palace but was converted into a more castle-like militaristic building in

11227-684: Was fragmented. Harran was an important city to the various local Muslim rulers as a counterweight to the nearby crusader states . Numayrid control of Harran came to an end in 1081 when the city was captured by the Uqaylid dynasty. It was then under the control of various Turkish princes; first Jikirmish of Mosul (1102–1106), then the Artuqids of Mardin (1106–1127) and then the Zengid dynasty , which captured Harran under Imad al-Din Zengi in 1127. In

11336-479: Was later incorporated into the Mitanni kingdom in the 16th century BC. Harran was conquered from Mitanni by the Assyrian king Adad-nirari I ( r.  1305–1274  BC). The city would not be firmly incorporated into Middle Assyrian Empire until the 1100s BC, before which it was often occupied by Arameans . Under Assyria, Harran grew into a fortified provincial capital second in importance only to

11445-419: Was likely the decreasing water supply. It was impossible to sustain the population size of Harran with its water storage systems in disrepair and its wells no longer producing enough water. Another possible reason for the abandonment was the difficulty to retain and defend Harran and the little strategic value offered by the city in return. Harran was regained from the Mongols by the Mamluk Sultanate later in

11554-542: Was often contested between the Roman and Parthian (later Sasanian ) empires. In 53 BC Harran was the site of the Battle of Carrhae , one of the worst military defeats in Roman history. The Harranian moon cult of Sin proved to be enduring and lasted long into the Middle Ages , known to have existed as late as the 11th century AD. Harran was captured by the Rashidun Caliphate in 640 and remained an important city in

11663-491: Was repaired under the Ottoman sultan Selim I ( r.  1512–1520 ) though it again declined in importance after his reign. The Ottomans continued to use the castle, and also built a new smaller mosque in the southern part of the city, but Harran gradually declined over the course of Ottoman rule and was eventually entirely abandoned as a permanent settlement. Harran has over the last five hundred years mainly been used as

11772-581: Was the Turkish Southeastern Anatolia Project , launched in the 1970s, which through irrigation efforts transformed the formerly dry desert plains surrounding Harran into productive agricultural fields. Harran received its own plan for future development in 1992. The ruins of the ancient city were placed on the Tentative list of World Heritage Sites in Turkey in 2000. Accelerated economic and demographic growth in Harran

11881-544: Was typically located near or on the border of the Roman (later Byzantine) and Parthian (later Sasanian ) empires. Harran frequently changed hands between the two empires but was in practice often more or less independent. In 53 BC, the city was the site of the Battle of Carrhae between the Romans and Parthians, in which the Parthian general Surena defeated and killed the Roman triumvir Marcus Licinius Crassus , one of
