St. Mary's Co-Cathedral

St. Mary’s Co-Cathedral on Armenian Street is distinguished by its history as one of the oldest Catholic churches in Chennai, dating back to sixteen fifty-eight. It was originally established by the French Capuchin missionary Ephrem de Nevers, who first built a simple open chapel at this site. While the structure has been rebuilt and expanded several times over the centuries, most notably in sixteen ninety-two and seventeen eighty-five, it maintains its role as a spiritual center in the middle of a dense commercial district.
