The Monastery of Mor Yakub lies in a valley West of the village of Ṣalaḥ. Its foundation dates back to the 5th or 6th century, based on comparisons with the plan of Mor Gabriel complex and to the tradition that it was founded on the site of the martyrdom of the Egyptian monk Mor Barshabo, and his disciples by Mor Yakub(Hans Hollerweger et al., Lebendiges Kulturerbe : Turabdin : Wo Die Sprache Jesu Gesprochen Wird. Freunde des Tur Abdin, 1999: 124-27). Following the death of its founder in 421 CE, it flourished greatly.
