St. Mary Church, currently known as Sharq-e Assur (West of Assur), lies in Qods street, Urmia City, and is one of the unique historical monuments of Assyrian People in Urmia.
The present view of the church belongs to Sasanid period which contains interesting vaults and beautiful symmetrization is comparable with the architecture of Sasanid fire temples. According to Assyrian and Christian authors, this monument used to be a fire temple and one of the famous temples of Zoroastrians.
St. Mary Church has been refurbished several times and made asymmetric. It seems that the first refurbishment was done in 642 AD at the instigation of the then Sultan's sister of China. In 1963 and 1964, a new tower was added to the church, and the church was refurbished.
