When Henry VI laid the foundation stone for King’s on Passion Sunday 1441 he aspired to have his college, and in particular its Chapel, without equal in magnificence in either Cambridge or Oxford. His successors saw his aspiration realised, at least as far as the Chapel is concerned – the rest of the college is not among the most beautiful in either city. Hiding in the grandeur are a myriad of fascinating details, such as this bat-like demon on the window of the Whichcote Chapel.
