We know that Looking Back readers enjoy a little teaser every now and then. So we have found this photo in the archive and wonder how many of you can identify it.

It is part of a plaque giving directions to various landmarks and towns from a specific point. You might be able to work out where it was from the various co-ordinates or you might just remember it.

A clue - it was connected to the military.
