In 1895, the then Archbishop Mgr. Gandhi consecrated the Archdiocese of Pondicherry to the Sacred Heart of Jesus and wished to build a new church in devotion of Sacred Heart of Jesus. Rev.Fr. Telesphore Welter, the parish priest of Nellithope prepared the building plan and parish priest of Cathedral Rev.Fr.Fourcaud commenced the construction of the new Church in 1902 at the Southern side of Pondicherry. The blessing of the church and the first mass was held at the western wing of the present church by Mgr. Gandhi on 17, December 1907 and the new parish surrounding this Church has been established on 27, January 1908. This oriental specimen of Gothic architecture contains rare stained glass panels depicting events from the life of Christ and saints of the Catholic Church.
