Armenian Church, Chennai, Armenian religious building in George Town, Chennai, India.

Saint Mary Church of Chennai, on Armenian Street in George Town, is a white church with a symmetrical facade. Its curved gable carries the number 1772 above a cross relief, while the number 1712 sits between two dark brown canopies over rectangular windows. A central dark double door opens beneath a small dome with a cross, and three short columns stand near an arched opening to the lower left.

The church was first built in 1712 on the private chapel grounds of Aga Shawmier, who succeeded Coja Petrus Oscan as leader of the Armenian merchant settlement. It was consecrated in 1772, the year shown on the facade. After decades of disuse from storm damage, the Calcutta Armenian diaspora funded a full restoration, and the church was reconsecrated in November 2008.

The church was a gathering place and spiritual center for Armenian merchants living in the city. Today, the graves and inscriptions on the grounds tell the story of traders who settled here centuries ago.

The church stands on Armenian Street in George Town and admits visitors from 9 am to 2:30 pm. The belfry with its six bells adjoins the main building, and the graves of about 350 Armenians lie across the grounds. The caretaker rings the bells on Sundays at 9:30 am.

The six bells, cast between 1754 and 1837, range from 21 to 26 inches and weigh about 150 kg each; two were made by Mears & Stainbank of London's Whitechapel foundry. Harutyun Shmavonyan, editor of the first Armenian periodical Azdarar, is buried in the church grounds.
