The boy became known as Little Saint Hugh, to distinguish him from Saint Hugh of Lincoln, but he was never canonised. The cathedral benefited from these events because Hugh was seen as a martyr, and many devotees came to the city and cathedral to venerate him.

In 1955 a plaque was placed near "the remains of the shrine of 'Little St Hugh in the cathedral, that decries the "Trumped up stories of 'ritual murders' of Christian boys by Jewish communities."

On the north side of the cathedral is the “Dean's Eye” which survives from the original structure of the building and on the south side is the “Bishop's Eye” which was most likely rebuilt circa 1325–1350. This south window is one of the largest examples of curvilinear tracery seen in medieval architecture. Curvilinear tracery is a form of tracery where the patterns are continuous curves. This form was often done within pointed arches and squared windows because those are the easiest shapes, so the circular space of the window was a
