WHEN delving into The Northern Echo's photo-library, you have to think like a librarian.

All these pictures come from the packet marked "Durham F", so we've got pictures of fires and festivals.

We've also got some pictures that don't seem to fit in at all and which we've filed under "flummoxed".

  • If any of the images trigger any memories, or if you have any information to share about them, please email chris.lloyd@nne.co.ukThe Northern Echo: LAID BARE: Durham castle from Palace Green in an undated photo which we reckon was taken in the late 1920s – there are no people, no cars, no scaffolding, no hoardings and not even any leaves
