Up until recently, i worked in the building next to the Cathedral on Norfolk row, Up on the second floor.
From the side windows, all we could see was the side of the church, and the stained glass windows. One day as i was on the phone, looking through the office window, i noticed something that i’d not noticed before - and certainly wouldn’t ever be seen from the street - see if you can spot it !! (Top right of window)
I also took a shot of the window just before Christmas after dark, as again, not something anyone would see !!
