St. Mary's Cathedral Church is one of the famous religious as well as tourist places in Jalandhar. The Old Church was constructed by Rev. Fr. John Macodnnel in 1947, in the memory of St. Patrick. In 1955, the Catholic Mission of the Indian Punjab was raised to the status of Apostolic Prefecture, with its headquarter at Jalandhar. The church in the city subsequently became the Cathedral or the Mother Church of Punjab. The demolition of the Old Church began on 15th February, 1987. In 1987, the foundation for the New Church was laid.

Dr. Symbhorian Keeprath Bishop of Jalandhar Diocese on 19th April, 1987. The roofing of the basement, the balcony and the main church were done on 19th September, 19th November and 19th December, 1987 respectively. The church was looked after by various chaplains appointed to Jalandhar, from the Diocese of Lahore. The design of the Church reflects the unique cosmo-culture of the Punjabi tradition of the state.
