Derelict doorway

We took the little family for a pizza lunch today. Margot was in great form, eating anchovy and sausage off the pizza, staring at her grandparents, taking an interest in passers-by. She didn't quite get the significance of the new bootees but her parents did. Something for the coming winter.

An afternoon walk got me to this doorway. What lurks behind No. 677?

Thanks for hosting Marlieske. Have a great start to the week.
