This is a picture of the 'lost street' under Renshaw Street. I have other pictures of this too, but have contacted the press over this and feel that they should have first view of all the other pictures.
What you are seeing is the small 'road' running underneath Renshaw Street. You drop down through the grid and end up in a square room, blocked off by two bricked up door arches, but turning a corner you come to the below view. On the left you can see the remains of the bricked up doors with their stone lintels at the top and the blocked up windows with their stone sashes. At the end of the passageway, there was a right turn, which then led to more of the same. This then turned left again and it was blocked up by an arched door (bricked up).
A handful of people know the location of this 'street' and I can guarentee that this is 100% true, that it is underneath Renshaw Street.
