This church was built in the sixth century A.H. (12th century AD) and in his travel chronicles, Marco Polo, the famous Venetian traveler who lived during the eight century A.H. (14th century AD), referred to this church on his way to China. For so many years, Saint Mary's served as the seat of the Azarbaijan Armenian Archbishop. It is a handsomely built edifice, with different annex buildings sprawled on a large area. A board of Armenian peers are governing the well- attended church.
