Walajabad was a sub station of the Capuchin Mission of Madras with its centre at Arcot. In 1888 this mission came under the jurisdiction of the old Mylapore diocese with the rural popluation of 1000 Catholics.These Catholics could have been in the historical 83rd Wallajah Light Infantry Regiment. In an epidemic of cholera most of the people perished and their graves still remain. Later with the formation of the Archdiocese of Madras-Mylapore, the Archbishop Louis Mathias built the Church and blessed it in 1961, and further he constructed a school and a Convent which were blessed by the Auxiliary Bishop of that time.
