The St. Mary church is a historical church in Isfahan, Iran.
In the 17th century the Armenian people of the Julfa quarter built a small church, the name of which was Hakoup. The Hakoup church was the oldest church of Julfa quarter, and was built strictly for the religious needs of the people, and didn’t have any kind of decorations. But as the Armenian population in Isfahan increased, the church became insubstantial. So one day, a wealthy silk merchant named Khaje Avdik came to the church, and when he couldn’t attend a religious ceremony because the church was full, he decided to expand the church. He decorated the church with lights, silver and gold chandeliers, and valuable canvases and paintings. He rebuilt the entire church using his own personal funds and named it St. Mary church. Khaje Avdik was then buried in the church after his death. Two large paintings painted by European artists have been bought by an Armenian businessman and have been donated to the church.
