St George’s Gardens, the park on the site of the former churchyard of St George in the East in Stepney, is a neat, peaceful place – when I visited, the play area was full of children, and other people were relaxing on benches or looking at the old monuments near the church.  In the midst of all of this is a derelict building that looks terribly sad and out of place.  However, this forlorn little building has a fascinating history that includes that most infamous of East End criminals, Jack the Ripper, and later became a pioneering centre for the education of local children.
