What the eye can’t see, a virtual tour of Cambridge can reveal! I show my original photos of the sights that are not easily accessible or are currently closed to the public, so that you can catch a glimpse of an inner court of a college, a staircase leading to students’ rooms, a historic lecture theatre, a scientific instrument from an exhibition that was used for a ground-breaking discovery, a graduation ceremony in June, and even the roof of King’s College Chapel.
