Early history According to archaeological and traditional accounts, the site of the monastery was originally occupied by a temple dedicated to the
Assyrian sun-god
Šamaš, dating back to . The temple's massive stone vaults, constructed without mortar, are still preserved beneath the monastery. One of its windows is aligned to catch the sunrise, suggesting its use in ritual observances and sacrifices. In
late antiquity, the complex was transformed into a Roman citadel, later expanded into a Byzantine fortress. When the Romans abandoned the site in the late 5th century, it was converted into a Christian monastery by Mor Shlemon (Solomon) in 493 AD. Architectural remains from this period, including floor
mosaics, are still visible within the monastery. The oldest surviving church, dedicated to the
Virgin Mary, dates from the 5th–6th centuries and features four altars, with carved wooden sanctuaries added in 1699. It was raided and destroyed by the
Persians in 607 AD when they conquered the region from
Byzantine forces, leaving the monastery deserted afterwards.
Ananias (Hananyo) was educated and ordained as a monk at the
Monastery of Mor Mattai near
Mosul. He was later ordained as the metropolitan bishop of Mardin and Kafartut, undertaking major restoration of the monastery. He also established a grand library of manuscripts, and under his leadership, the monastic community grew to about 80
monks. From this period onward, the monastery became a prominent religious centre and has since borne his name as Mor Hananyo Monastery. Ananias was succeeded by his disciple Ignatius I in 816, who was the 80th bishop of the church and further expanded the monastery's structures and its library.
Medieval history In 1034, the 67th
Patriarch of Antioch, Dionysius IV Yahya (1031–1042), settled in
Amid (modern-day
Diyarbakır) after seeking the protection of the Muslim rulers. He also spent some time in Mor Hananyo, becoming the first patriarch to do so. The region was invaded by
Islamic forces in 640, and in 1106, it came under the control of the
Artukids. The monastery was later abandoned and re-founded by Yuhanon (John) IV, bishop of Mardin, who renovated the complex between 1125 and 1148, after which it was designated the patriarchal residence before his death on 12 July 1165. The region was devastated by Mongol invaders in 1394 and in subsequent years. In 1166, Patriarch
Michael the Great was enthroned there, initiating nearly eight centuries of patriarchal presence. During the 14th–15th centuries, the monastery endured devastation. In 1396,
Tamerlane attacked Mardin for the second time, killing, looting, and taking many captives. As a result, some of its monasteries were destroyed, including the walls, cells, and the door of Mor Hananyo.
Kurdish raiders inflicted great damage on the monastery and surrounding villages over the years as well, including in 1516. The monastery further deteriorated due to neglect. Patriarch
Ignatius II rebuilt the monastery between 1696 and 1699, adding the
Church of the Patriarchal Throne which was intended for synods and patriarchal elections. Later patriarchs would also gradually renovate it. The patriarchal throne and many relics are still located in the monastery, in addition to the tombs of various patriarchs.
Modern history Since the 13th century, the monastery has faced repeated
Kurdish incursions, looting, and desecration. The wider insecurity of southeastern
Anatolia, where most
Assyrian Christians lived, left their communities vulnerable to frequent raids by neighbouring Kurdish Muslim groups. As the patriarchal seat of the Church, the monastery was directly affected.
Horatio Southgate, an American missionary who visited in the 19th century, noted that Mor Hananyo had been invaded and occupied by Kurds. Regional upheavals, including the rebellion of
Badr Khan in the 1840s, brought devastation to Assyrians of both the
Syriac Orthodox Church in
Tur Abdin and the neighbouring
Church of the East in
Hakkari. Some of the worst violence, however, was unleashed in the massacres beginning in 1895. During this period, the monastery was repeatedly occupied by Kurdish Muslims, who neglected and abused the site. Ancient manuscripts were destroyed, with some used as
gunwadding for rifles or as kindling for fire, and clergy were powerless against local violence. The monastery's condition deteriorated rapidly, leaving it little more than a ruin by the time restoration was attempted. Despite this, the monastery also became a refuge for displaced villagers, particularly during the
massacres of 1895. Syriac Orthodox manuscripts preserved at the monastery contain eyewitness accounts of the atrocities in
Syriac,
Arabic and
Garshuni. There were widespread killings of men, women, childrenm and clergy; burnings of monasteries, homes, and churches; and the ransacking of villages across Mardin, Diyarbakır, and the surrounding regions. More than fifty villages were reported as emptied of their indigenous Assyrian population. Refugees who fled to the monastery were ordered by
Ottoman officials to return to their ruined villages, where starvation, exposure, and renewed attacks caused further deaths. Contemporary letters also document appeals to the patriarch to intervene in cases of abduction and forced conversion, including an
Armenian plea to rescue his wife and child from Kurdish captors who claim the wife
converted to Islam after her kidnapping, and thus will not be returned. The violence has been described by scholars as a precursor to the
Assyrian genocide of 1915. The monastery itself sheltered hundreds of women, children, and the elderly during the crises. One account recalls that only the intervention of an
Ottoman army officer, moved to pity by the state of the refugees, prevented the complete massacre of those inside. Nevertheless, the villages surrounding the monastery — including Bnabil, Dara, Bkeera, Qillath, al-Mansuriyah, Macsarta, Baval, Sour, al-Qusour, al-Qalsatma — were devastated, with their Christian populations eradicated. The destruction extended across Diyarbakır,
Nusaybin,
Azekh, and
Siirt, where the
Chaldean Catholic archbishop and scholar
Addai Sher was murdered. Further looting of farmland and livestock was reported by villagers who resorted to begging to survive. A state of anarchy prevailed, with both ecclesiastical and local civil authorities rendered helpless before the tyranny of Kurdish tribes, who operated undeterred under the blessing of the
Ottoman state. They pillaged, murdered, raped, kidnapped, and harassed the indigenous Christians of the monastery and surrounding villages, who were also subjected to
forced conversion to Islam against their will. The violence reflected deep-rooted attitudes that persisted long after these events. During the
Seferberlik massacres, part of the 1915
Assyrian genocide,
Kurdish tribes besieged the monastery, intent on killing refugees from surrounding villages. One Assyrian man disguised himself to smuggle food past the besiegers. Despite centuries of upheaval, Mor Hananyo remained the patriarchal seat of the Syriac Orthodox Church for nearly a millennium. This ended in 1924, soon after the
establishment of the Turkish Republic, when
Patriarch Ignatius Elias III received a telegram from
Mustafa Kemal Atatürk delivered via the governor of Mardin, declaring:The clerical leader in the black cassock [the Patriarch] should leave Turkey immediately and should never ever return! The patriarch was stripped of Turkish citizenship, and the patriarchate relocated first to
Homs, and then to
Damascus, where it remains today as the
Syriac Orthodox Patriarchal Archdiocese of Damascus. Mor Hananyo, however, would continue to function as a monastic centre, despite everything. Over its history, at least 21 Syriac Orthodox synods were convened there, the last on 30 November 1916, when Ignatius Elias III was elected
Patriarch of Antioch. == Church architecture ==
