One of two things:
I don't know a lot about the prison. New Hall the college, unlike
New College, Oxford is still quite new, having been founded in
1954. It consists of a collection of rather grubby, initially white buildings in the west of
Cambridge (next to
Fitz), all surrounding a large
breast-shaped dome.
Academically, it's not doing all that well, a fact painfully brought home by their recent embarassing performance on
University Challenge.
The college also has an important collection of women's art, and a lovely cat.
