Dayro d'Mor Aho

Dayro d'Mor Aho

Dayro Mor Aho is located in the Tur Abdin region, specifically 38 kilometers northeast of Nusaybin in the Mardin Province of Turkey. This Syriac Orthodox monastery is believed to have been founded in the 6th century, possibly earlier, and is associated with Mor Aho, who is said to have brought relics of the Holy Cross from Constantinople. The monastery's historical significance is underscored by its connection to these relics, which were reportedly placed in different parts of Tur Abdin.

The monastery complex features a rectangular plan with a courtyard, fortified walls, and a rectangular tower, resembling a castle in its structure. Constructed using rubble stone masonry, the monastery, while largely in ruins, still retains some of its original architectural elements. Within the monastery grounds are several water wells and cisterns, and evidence suggests that the complex once extended over a much larger area.

Dayro Mor Aho contains the remains of at least two churches. One is relatively small with a north-south axis, while the other includes an apse constructed with large cut stones. The monastery's tower is a prominent feature, possibly used for defense or seclusion. Despite its ruined state, Dayro Mor Aho is considered an important example of Syriac architectural heritage, and its relationship to the surrounding landscape further enhances its significance.
