Crumbling Arch

After work I went for a walk since the torrential rain from earlier in the day had stopped.  I found two of these arched windows which were part of a ruined building.  I have no idea which street this was on - I think it was Eton Street or something like that - because I was actually lost.  I knew which direction I was heading in but I just took a dander round some streets I have never encountered before.  I like my Magical Mystery Tours of Edinburgh.
