I think this is what we 70s students knew as Room One, recognisable by the tiered benches and desks. It looks similar to the photo below of the Criticism Room but may be different because of the lecturer's bench.

The model classroom awaits students, children and lecturers in the Criticism Room. A fearsome thought. Is this room also Room One I wonder?

The Library. I'm unsure whether this room is in the main building or whether each hall / hostel would have their own library.
