Construction of St. Mary's Church began in 1678 and was completed in 1680, making it the oldest Anglican church in India and one of the oldest British buildings in the country. It was built to serve the spiritual needs of the British East India Company officials and their families stationed at Fort St. George. Over the centuries, St. Mary's Church has witnessed significant historical events, including serving as a refuge during sieges and wars. The church's register contains records of births, marriages, and deaths of prominent figures in colonial Madras. It stands as a testament to the enduring legacy of the British presence in India.
