Near Aldgate, London

I'm not sure if this spot has a name because its not a garden no-one can sit there its just a green space filled with plants. Its at the top of Aldgate close to St. Botolphs Church. I was standing on Duke's Place behind the famous St. John Cass Primary School, its a very busy junction and probably an overlooked spot. I believe the blue building is St. Botolph House and would be entered via Houndsditch.
