When my parents were first in Calcutta after they moved from Madras the family lived in a rented apartment connected to Bishop's College at Ballygunge in Calcutta. Today I came across some photos of the college at this time, I could be a few years out with the date. The first photo below is of the student accommodation that looked out onto a grassy square where the students used to play volleyball for recreation.
The second photo is of the Chapel in the college grounds which was just over the fence from where the family ended up living at 67 Ballygunge. You can see a student ringing the chapel bell calling the congregation to attend a service. Now I think back I can remember the bell being rung.
The final photo shows a group of students having a meal.
