The inside walls of this stone structure originally bore some beautiful murals, highlighting the events in the life of Mary, painted during the time of the first Rector. Since they had faded with the passage of time, they have been replaced by beautiful fiberglass murals depicting the same story of Mary. These large panels were prepared by Sr. Vimala (PDDM) and a group of artists from Goregaon, under the personal supervision of the former Rector, Msgr. Nereus Rodrigues.
