Changes to historic towns like Richmond seem almost imperceptible, but while the architecture may survive largely untouched, details tell the story of the passage of time.

These photographs of Richmond show a market square that is unmistakable, but features like shop awnings – rarely seen in the modern era – instantly date the scene.

Motoring enthusiasts, or maybe just those with keen memories, will also be able to date the early images by the make and model of vehicles present.

A pram of robust construction is another clue, along with the fashions of the day, which might suggest these show a 1930s or early post-war community.

The archive images are among more than 6,500 historic views of North Yorkshire available at the County Record Office. Buy a copy or browse the collection.
