St. Andrew’s Church is one of the oldest churches in Reddiarpalayam area of Puducherry. The original structure was built in Gothic architecture in 1745 by Kanakaraya Mudali, the longest serving dubash of the French East India Company. During the opening of the Church, Mudali hosted a feast that included all castes and religions, the first of its kind that is recorded in the history of South India. It is believed that the Church was destroyed by the British in 1761 and was later rebuilt in 1830. It is the first Church in South India to have inscriptions made in Tamil during the times. St. Andrew’s Church is a working church with hourly prayer and daily services and follows Roman Catholic sect of Christianity. The priests in the church were originally only French, but during modern times, Tamil people were also allowed. In modern times, the Church is administered by the Archdiocese of Pondicherry and Cuddalore. Mass is performed in the church from Monday to Friday on 5 a.m., and 5 p.m. on Saturdays and 5 a.m., 6 a.m. and 5 p.m. on Sundays. The feast of the church is celebrated during the Christmas times for eight days, starting with flag hoisting on 24 January and ending on 2 January.
