Derelict Sunday

Thank you Evolybab for taking on this challenge.  I was trying to photograph this Magpie, but he wouldn't settle anywhere for long enough.  Then he landed onto the roof of a building behind our house and I realised I had my Derelict Sunday shot.  This building is in no way derelict, in fact it is in use all the time.  However this upper window and the part of roof below it have definitely seen better days.  You can only see it from certain angles and I doubt any one has been up there for years.
