Taşköy (Arabic: اربو; Kurdish: Erbo;[2] Syriac: ܐܪܒܘ, romanized: Arbo)[3][a] is a neighbourhood in the municipality and district of Nusaybin, Mardin Province in Turkey.

[11] According to the account of the priest Addai of Basibrina in c. 1500 appended to the Chronography of Bar Hebraeus, Arbo survived Timur's invasion in 1401 (AG 1712) by the intercession of Dioscorus Behnam Shatti, metropolitan bishop of Beth Risha, after he had appealed directly to Timur's son Mīrānshāh to spare his village and had received a kerchief as a sign of his decision.

[12] However, Arbo, including the Monastery of Mar Shim’un (Simon), was destroyed alongside Nisibis and the villages of Hbab and Ma’are by Malik al-Adel, the governor of Hasankeyf, in 1403 (AG 1714).

[20] Iyawannis II, metropolitan bishop of Beth Risha, was killed at Arbo by the emir of Cizre in 1505 according to a Syriac memro (metrical ode) written by a priest from Habsnas.

[24] Ignatius Barsoum of Arbo, previously metropolitan bishop of the Mor Malke Monastery, was patriarch of Tur Abdin in 1740–1791.

[24] Bedir Khan Beg reportedly rode his horse over the remains of a church destroyed by his men at Arbo.

[30] The Syriac Catholic bishop Gabriel Tappouni recorded that the village was populated by about 600 Assyrians in 100 families and were served by one priest in 1913.
