St. Matthew’s Monastey, Mosul, Kurdistan, Iraq

High on Mount Alfaf above the Nineveh Plains stands Mar Mattai, founded in 363 AD and counted among the oldest Christian monasteries in existence. Still inhabited by monks and a bishop, it has been a center of Syriac learning and, again and again across the centuries, a mountain refuge for persecuted Christians — most recently in 2014.

Mar Mattai, the Monastery of Saint Matthew, sits at around 820 meters on the flank of Mount Alfaf, about twenty kilometers northeast of Mosul, looking out over the Nineveh Plains. It was founded in 363 AD by Mor Mattai the Hermit, who fled persecution under the emperor Julian with a small band of monks and settled on the mountain — making it one of the oldest Christian monasteries anywhere and the oldest of the Syriac Orthodox Church. For sixteen centuries it has been a living house of prayer.

Its long history is a history of learning and of endurance. Mar Mattai rose to be an episcopal and then a metropolitan see, a great center of monastic scholarship and manuscript production; a fire in 480 AD destroyed part of its celebrated library, and conflict and time have reduced its manuscripts to a small surviving collection. The monastery has also served, repeatedly, as a place of safety. In 2014, as ISIS advanced across the plains and halted only a few kilometers short, the monks and bishop remained, the monastery sheltered displaced Christians, and its manuscripts were moved to safety. The Kurdistan Regional Government later renovated and secured the site.

To arrive is to climb a winding mountain road to a fortress-like complex of stone, to find the tomb of Mor Mattai still venerated, monastic prayer still kept, and a community still in place — and to look out over a plain that has been Christian for far longer than most of the world's churches have existed.

Founded in 363 AD by Mor Mattai the Hermit, the monastery became the oldest Syriac Orthodox house, a center of learning, and a refuge in times of persecution.

Mor Mattai fled persecution under the emperor Julian the Apostate, traveling with twenty-five monks, and settled as a hermit on Mount Alfaf, founding the monastery in 363 AD. It grew into a great center of monastic learning and an ecclesiastical seat, first episcopal and later metropolitan. A fire in 480 AD cost it part of its library. Across the centuries it was damaged and rebuilt many times and served repeatedly as a refuge for Iraq's Christians, a role it filled again in 2014 when ISIS reached the edge of the plains. Syriac tradition also links the monastery to the Behnam and Sarah legend, in which Mor Mattai healed Sarah and converted her and her brother — a story shared with the nearby Mar Behnam Monastery and hagiographic rather than documented.

Syriac Orthodox Christianity, within the early Syriac monastic tradition of Mesopotamia.

An ancient living monastery whose sanctity rests on extreme antiquity, monastic continuity, and a recurring role as mountain refuge.

Mar Mattai's power is the power of duration. Monastic prayer has been kept here, with interruptions, since the fourth century — a thread of continuity that few places on earth can match. The mountain setting reinforces it: a fortress of stone clinging to a steep flank, withdrawn from the world yet commanding a vast view over the plains where Christianity took root early. And running through its whole history is the role of refuge — the monastery has sheltered the persecuted again and again, most recently in 2014, when monks and bishop held their ground as ISIS advanced. Antiquity, silence, and survival converge here.

A hermitage and monastery founded by Mor Mattai and his monks, which became a major center of Syriac monastic life, learning, and ecclesiastical authority.

Founded 363 AD; rose to an episcopal see in the late fifth century and later a metropolitan see; its library was partly lost to a fire in 480 AD; renovated and secured by the Kurdistan Regional Government after 2014.

Daily monastic prayer and liturgy, veneration at the tomb of Mor Mattai, and an annual feast on 18 September that draws Christians of several denominations.

Daily monastic prayer and liturgy; veneration at the tomb of Mor Mattai; and the annual feast of Mor Mattai on 18 September, which gathers Christians of various denominations in pilgrimage.

Monastic life continues with monks and a bishop in residence; pilgrimage and visitation continue through the year and peak at the September feast.

Move with the rhythms of the monastery: keep quiet, observe rather than interrupt, and let the silence and the view do their work. Reflection on endurance, faith under persecution, and the long continuity of Christian presence in Mesopotamia fits the place for visitors of any background.

A serene fortress-like monastery on the mountainside with sweeping views over the Nineveh Plains, a deep sense of antiquity, and a welcoming community.

Visitors describe a stone monastery built almost into the cliff, reached by a winding climb, with terraces and walls that give it the look of a fortress. From its height the Nineveh Plains spread out below, and the sense of antiquity is immediate. Inside are the tomb of Mor Mattai, venerated for sixteen centuries, and a small surviving collection of manuscripts that hints at the great library the monastery once held. The monastic community is described as welcoming, and the rhythm of monastic prayer continues; the silence and the long view together produce the strongest impressions.

Allow time for the climb and the views before going inside. The tomb of Mor Mattai is the devotional heart; the surviving manuscripts and the terraces overlooking the plains complete the visit. Early morning is the quietest time and gives the clearest views over the Nineveh Plains.

Mar Mattai is read as one of the oldest living monasteries on earth and as a recurring sanctuary in times of danger.

Scholars describe a genuinely ancient, fourth-century Syriac Orthodox monastery and historic seat of learning and ecclesiastical authority, repeatedly damaged and rebuilt across its long history; one of the oldest surviving Christian monasteries.

Syriac Orthodox Christians venerate it as the foundation of Mor Mattai and a sacred refuge, and its feast unites multiple Christian denominations.

Traditions of miraculous healing are associated with Mor Mattai — above all the healing of Sarah — and with the protective sanctity of the mountain refuge.

The historicity of the Behnam, Sarah and Sennacherib founding legend is uncertain, and much of the monastery's earliest fabric and many early manuscripts were lost to fire and conflict.
