In 1796, the ban was lifted and the Portuguese community of Calcutta decided to build a modern Church and it is thus that the present Church of the Most Holy Rosary came to be. The present Portuguese Church was designed at a cost of ₹90,000 by James Driver. A striking and unique feature of the Church are its two giant towers which look almost like minarets, topped by crown shaped cupolas. In front is a neat pedimented porch. The Church was consecrated on the 27th of November, 1799. The cost of construction was borne by Joseph Baretto of the well-known Calcutta banking family. It is currently the seat of the Archbishop of the Roman Catholic Archdiocese of Kolkata.
Apart from the two towers, the eye-catching exterior of the cathedral is adorned with a decorative pediment rendered in vibrant hues. An arched entrance leads to a colonnaded interior with wooden pews set on either side of the aisle. The main altarpiece, painted white with gold highlights, looks resplendent when light from the circular stained-glass windows set high above filters in.
The statue of the Virgin Mary with the infant Jesus occupies pride of place on the massive altarpiece. Another interesting feature of the cathedral is the 14 wooden panels in bas relief, which depict the 14 Stations of the Cross.Portuguese Church located on the Murgihata Street just off the Brabourne Road and Canning Street crossing. Although located in one of the busiest localities of Kolkata it serves as a oasis of peace like most of the Kolkata Churches.
