One of the most famous artworks that are present in this church is the painting of The Last Supper by Johann Zoffany painted in the year 1787. The one that you see now has been carefully restored in the year 2010. The uniqueness of this last supper painting is that Zoffany used real life subjects for the various faces in the painting. Some of the famous subjects involved a Greek priest, Father Parthenio who was used for Jesus, W.C. Blacquiere the police magistrate of Calcutta was selected for John and infamously auctioneer William Tulloh was used for Judas.
Zoffany added some local Indian flavor to this famous painting by adding small features like the Bisti (goatskin water bag) and an Indian sword thus making it really different from the rest of the Last Supper paintings.
