Between 1924-25, the church was extended to accommodate the increasing number of people. The church was completely remodelled during the Vicarship of Msgr. Stanislaus Pereira to give it a modern appearance.
The year of consecration of Our Lady of the Rosary Church on Dockyard Road, Mazagaon, is inscribed on the outer wall. In 1794, this new church was built a few metres away from the old Gloria Church, which till 1794 was the only church in Mazagaon.
The wrought iron grilles on the boundary wall were installed in 1860 with the marking NRS, which stands for Nossa Senhora do Rosario, or “Our Lady of the Rosary”.
