Experiment House

Experiment House was the boarding school that Eustace Scrubb and Jill Pole attended and where they met. It was a poorly managed school, where no one was ever punished, and as a result there was a lot of bullying, and not much learning. Eustace and Jill were trying to escape from bullies when they accidentally entered Narnia through a door in the school grounds outer wall in The Silver Chair. At the end of that story, Eustace, Jill and Caspian are allowed by Aslan to mete out some punishment to the bullies with the flats of their swords and a riding crop.

When Professor Kirke makes his often-heard comment, "...what do they teach them at these schools?", this may be the sort of school he is referring to.

Trivia
Experiment House was inspired by C.S Lewis's nearly always bad schooling experiences.
