u/Extension_Cost_5522

I was walking down a small road off Salmon Lane (E14) called Copenhagen Place. I came across a pretty regular looking East London estate. I noticed that one of the walkways up to the estate has this strange layout of metal bars which make ridiculously difficult to get to the exit on the other side. I was thinking that maybe it was to enforce a queuing system for something that isn’t here anymore? But I can’t imagine there would have been a venue there or something because the outside bit looks in keeping with the estate. I’d love to hear if anyone could provide more context about this.
