It's still there. In fact it would be very difficult to get rid of it, as it is basically a glazed gap in the structure of a grade 2 listed building. If Hitler didn't get it, it should last for a while yet.Another 'explanation' of the Green Ginger name is that it refers to excrement. So there's plenty of reasons for this street name. Take your pick from existing ones or, better still, make one up for yourself.
