The Citadel of Aleppo (Arabic: قلعة حلب, romanized: Qalʿat Ḥalab) is a large medieval fortified palace in the centre of the old city of Aleppo, northern Syria. It is considered to be one of the oldest and largest castles in the world. Usage of the Citadel hill dates back at least to the middle of the 3rd millennium BCE. Occupied by many civilizations over time – including the Greeks, Armenians, Romans, Byzantines, Ayyubids, Mamluks and Ottomans  – the majority of the construction as it stands today is thought to originate from the Ayyubid period. An extensive conservation work took place in the 2000s CE by the Aga Khan Trust for Culture, in collaboration with Aleppo Archeological Society. Dominating the city, the Citadel is part of the Ancient City of Aleppo, an UNESCO World Heritage Site since 1986 CE.^[1] During the 2010s, the Citadel received significant damage during the lengthy Battle of Aleppo.^[2][3] It was reopened to the public in early 2018 CE with repairs to damaged parts underway, though some of the damage will be purposefully preserved as part of the history of the citadel.^[4] The citadel was damaged by the 2023 Turkey–Syria earthquake.

History

The recently discovered temple of the ancient storm-god Hadad dates use of the hill to the middle of the 3rd millennium BCE, as referenced in cuneiform texts from Ebla and Mari.^[5] The city became the capital of Yamhad and was known as the "City of Hadad".^[6] The temple remained in use from the 24th century BCE^[7] to at least the 9th century BCE,^[8] as evidenced by reliefs discovered at it during excavations by German archaeologist Kay Kohlmeyer.

The patriarch Abraham milked his sheep on the citadel hill.^[9] After the decline of the Neo-Hittite Empire centered in Aleppo, the Neo-Assyrian Empire ruled the area (8th–7th century BCE), followed by the Neo-Babylonian Empire and the Achaemenid Empire (539–333 BCE).^[10]

Seleucid period

After Aleppo was ruled by the armies of Alexander III of Macedonia, Aleppo was ruled by Seleucus I Nicator, who undertook the revival of the city under the name Beroia. Medieval Arab historians say that the history of the citadel as a fortified acropolis began under Seleucus I Nicator.^[9] In some areas of the citadel there are up to two meters of remains of Hellenistic settlement. A colonnaded street led up to the citadel hill from the west, where the south area of Aleppo still retains the Hellenistic grid street plan.^[11]

Roman and Byzantine periods

After the Romans destroyed the Seleucid dynasty in 64 BCE, the citadel hill continued to have religious significance. Emperor Julian, in his 363 CE visit to Aleppo noted "I stayed there for a day, visited the acropolis, offered a white bull to Zeus according to imperial customs, and held a short talk with the town council about worshiping the deities." Very few physical remains have been found from the Roman age in the Citadel.^[10]

The Roman Empire was divided into two parts in 395 CE. Aleppo was in the eastern half, Byzantine Empire. During the clashes with the Sassanian king Khosrow II in the 7th century CE, the population of Aleppo is said to have taken refuge in the Citadel because the city wall was in a deplorable state. Currently, very few remains from the Byzantine period have been found on the Citadel Hill, although the two mosques inside the Citadel are known to be converted from churches originally built by the Byzantines.^[10]

Early Islamic period

Arab armies ruled over Aleppo in 636 CE. Written sources document repairs being made on the citadel after a major earthquake. Little is known about the citadel in the period of early Christianity and Islam, except that Aleppo was a frontier town on the edges of the Byzantine, Ummayad and Abbasid empires.^[10]

Sayf al-Dawla, a Hamdanid prince, conquered the city in 944 CE, and it subsequently rose to a political and economic renaissance.^[10][12] The Hamdanids built a reputedly splendid palace on the banks of the river, but moved to the Citadel after Byzantine troops attacked in 962 CE. A period of instability followed Hamdanid rule, marked by Byzantine and Beduin attacks, as well as a short-term rule by the Egyptian-based Fatimids. The Mirdasids were said to have converted the two churches into mosques.^[10]

Zengid and Ayyubid periods

The citadel rose to the peak of its importance in the period during and after the Crusader presence in the Near East. Zengid ruler Imad ad-Din Zengi – followed by his son Nur ad-Din (ruled 1147 CE – 1174 CE) – successfully unified Aleppo and Damascus and held back the Crusaders from their repeated assaults on the cities. Several famous crusaders were imprisoned in the citadel, among them Count of Edessa, Joscelin II, who died there, Raynald of Châtillon, and the King of Jerusalem, Baldwin II, who was held for two years. In addition to his many works in both Aleppo and Damascus, Nur ad-Din rebuilt the Aleppo city walls and fortified the citadel. Arab sources report that he also made several other improvements, such as a high, brick-walled entrance ramp, a palace, and a racecourse likely covered with grass. Nur ad-Din additionally restored or rebuilt the two mosques and donated an elaborate wooden mihrab (prayer niche) to the Mosque of Abraham. The mihrab disappeared during the French Mandate when it was destroyed.^[13]

Saladin's son, al-Zahir al-Ghazi, ruled Aleppo between 1193 CE and 1215 CE. During this time, the citadel went through major reconstruction, fortification and addition of new structures that create the complex of the Citadel in its current form today. Sultan Ghazi strengthened the walls, smoothed the surface of the outcrop and covered sections of the slope at the entrance area with stone cladding. The depth of the moat was increased, connected with water canals and spanned by a tall bridge-cum-viaduct, which today still serves as the entrance into the Citadel. During the first decade of the 13th century CE, the citadel evolved into a palatial city that included functions ranging from residential (palaces and baths), religious (mosque and shrines), military installations (arsenal, training ground, defence towers and the entrance block) and supporting elements (water cisterns and granaries). The most prominent renovation is the entrance block rebuilt in 1213 CE. Sultan Ghazi also had the two mosques on the Citadel restored, and expanded the city walls to include the southern and eastern suburbs, making the citadel the centre of the fortifications, rather than alongside the wall.^[13]

Mongol and Mamluk periods

The citadel was damaged by the Mongol invasion of 1260 CE and again destroyed by the invasion led by the Turco-Mongol leader Timur which swept through Aleppo in 1400 CE – 1401 CE.^[13]

In 1415 CE, the Mamluk governor of Aleppo, prince Sayf al-Din, was authorized to rebuild the citadel, which by then stood at the centre of a significant trading city of between 50,000–100,000 inhabitants.^[14] Sayf al-Din's additions included two new advance towers on the north and south slopes of the citadel, and the new Mamluk palace built on top of the higher of the two entrance towers. The Ayyubid palace was almost completely abandoned during this period. The Mamluk period also administered restoration and preservation projects on the Citadel. The final Mamluk sultan, al-Ashraf Qansuh al-Ghawri, replaced the flat ceiling of the Throne Hall with nine domes.^[15]

Ottoman period

During the Ottoman period, the military role of the citadel as a defense fortress slowly diminished as the city began to grow outside the city walls and was taking its form as a commercial metropolis. The Citadel was still used as a barracks for Ottoman soldiers, although it is not known exactly how many were stationed there. An anonymous Venetian traveler mentions some 2,000 people living in the Citadel in 1556 CE. In 1679 CE, the French consul d’Arvieux reports 1,400 people there, 350 of whom were Janissaries, the elite military corps in the service of the Ottoman Empire. Sultan Süleyman ordered a restoration of the citadel in 1521 CE.^[9][16]

Aleppo and the citadel were heavily damaged in the earthquake of 1822. After the earthquake only soldiers lived in the citadel.^[9] The Ottoman Governor of the time, Ibrahim Pasha, used stones from destroyed buildings in the citadel to build a barracks in the north of the crown. It was later restored under the rule of Sultan Abdülmecid in 1850 CE – 1851 CE. A windmill, also on the northern edge of the crown, was probably built around the same time.^[16]

French Mandate

Soldiers continued to be stationed in the citadel during the French Mandate (1920 CE – 1945 CE). The French began archaeological excavations and extensive restoration work in the 1930s CE, particularly on the perimeter wall. The Mamluk Throne Hall was also completely restored during this time and given a new flat roof decorated in 19th-century CE Damascene style. A modern amphitheater was constructed on a section of an unexcavated surface of the citadel in 1980 to hold events and concerts.^[17]

Modern day

The citadel in its present form is on a mound, which has an elliptical base with a length of 450 metres (1,480 feet) and width of 325 metres (1,066 feet). At the top this ellipse measures 285 metres (935 feet) by 160 metres (520 feet) with the height of this slanting foundation measuring 50 metres (160 feet). In the past, the entire mound was covered with large blocks of gleaming limestone, some of which still remain today.^[17]

The mound is surrounded by a 22-metre-deep (72-foot) and 30-metre-wide (98-foot) moat, dating from the 12th century. Notable is the fortified gateway, accessible though an arched bridge. This feature was an addition from the Mamluk government in the 16th century CE. A succession of five right-angle turns and three large gates (with carved figures) leads to the main inner castle entrance.^[17] In the interior of the Citadel, are the Weapons' Hall, the Byzantine Hall and the Throne Hall, with a restored decorated ceiling. Prior to the Syrian civil war, the citadel was a tourist attraction and a site of archaeological digs and studies. The amphitheater was often used for musical concerts or cultural events.^[17]

In August 2012 CE, during the Battle of Aleppo of the Syrian Civil War, the external gate of the citadel was damaged after being shelled during a clash between the Free Syrian Army and the Syrian Army to gain control over the citadel.^[18] In July 2015 CE, a bomb was set off in a tunnel under one of the outer walls causing further damage to the citadel, in an attempt for the Free Syrian Army to dislodge the Syrian Army.^[19] During the conflict, the Syrian Army used the Citadel as a military base, and according to the opposition fighters, with the walls acting as cover while shelling surrounding areas and ancient arrow slits in walls being used by snipers to target rebels.^[20] As a result of this contemporary usage, the Citadel has received significant damage.^[2][3][21]

The citadel was extensively damaged by the magnitude 7.8 2023 Turkey–Syria earthquake on February 6, 2023 CE.^[22] On 17 February 2024 CE, Citadel of Aleppo was reopened after the completion of the first and second phase of the restoration of southern forward tower (the entrance to the citadel), which was greatly affected by the earthquake.^[23] Also other phases of the citadel’s restoration have been revealed, including the entrance, the minaret of Great Ayyubid Mosque, and the façade of Throne Hall.

Internal sites

There are many structural remains inside the citadel. Notable sites include:

Entrance block

The enormous stone bridge constructed by Sultan Ghazi over the moat led to an imposing bent entrance complex. Would-be assailants to the castle would have to take over six turns up a vaulted entrance ramp, over which were machicolations for pouring hot liquids on attackers from the mezzanine above. Secret passageways wind through the complex, and the main passages are decorated with figurative reliefs. The Ayyubid block is topped by the Mamluk "Throne Hall", a hall where Mamluk sultans entertained large audiences and held official functions.^[24]

Ayyubid Palace and Hammam

Ghazi's "palace of glory" burned down on his wedding night and he escaped with the queen, but it was later rebuilt and today stands as one of the most important and impressive monuments in the citadel crown. The Ayyubids were not the first to build a palace on the citadel. Today, numerous architectural details remain from the Ayyubid period, including an entrance portal with muqarnas, or honeycomb vaulting, and a courtyard on the four-iwan layout, with tiling.^[25]

Laid out in traditional medieval Islamic style, the palace hammam has three sections. The first was used for dressing, undressing, and resting. The second was an unheated but warmer room, and this was followed by a hot room, and a steam room equipped with alcoves. Hot and cold water was piped through to the hammam with earthenware pipes.^[25]

Satura, Hellenistic Well, and underground passages

The construction in the citadel was not confined to above-ground. Several wells penetrate down to 125 m (410 ft) below the surface of the crown. Underground passageways connect to the advance towers and possibly under the moat to the city.^[25]
