St. Sarkis Church (Persian: کلیسای مار سرکیس; Official Aramaic (700-300 BCE);; Imperial Aramaic (700-300 BCE);: ܩܕܝܫܬܐ ܡܪܝ ܣܲܪܓܝܼܣ) is an ancient Assyrian church located in Sir close to Urmia, West Azerbaijan Province, Iran.[1] Also known as the Maar-Sargiz Historical Church, Marserkis Church, Marsarkis Church, and Sir Church.
Current building of the church seems to have been built between the 3rd and 5th centuries.[2] It is believed that St. Sarkis Church was built by the orders of Shirin (the wife of the Sassanian emperor Khosrow Parviz), who was a Christian.[3]
It is located on the slope of Mount Sir, 3 km southwest of the city of Urmia and is a pilgrim place of local Assyrian Christians.[4] Its architecture relates to Sassanid era. Its ceiling is in barrel vault and its thick walls are made out of irregular stones and sand-lime mortar. Altar lies on the east side and the church entrance in the south wall.[5] St. Sarkis Church consists of two parallel naves interconnected by a narrow passage. The southern nave is called Mar Sarkis (Saint Sergius) and the northern one Mar Bakus (Saint Bacchus). Both sides of the church style of arches are Sassanian and Tavizeh vault with a horseshoe-shaped cradle made.[6]
The gravesite nearby is the burial place of Joseph Gallup Cochran and his son Joseph Plumb Cochran.[7] [8]
