I AM a volunteer helper in our cathedral, involved in the children's programme.

Taking my little band of 15 juniors, we headed for the Trinity Chapel.

They were there for a potted history given a 'Horrible Histories' slant.

The Trinity Chapel gave them an instant introduction to horribleness which my imagination could never have matched.

A horde of aliens, in terracotta, 2m tall - Roald Dahl at his best with a hint of the Gruffalo - disfigured the place!

Where does the cathedral get these grotesque offerings from?
