Market towns have a reassuring continuity and these images of Thirsk down the decades reveal just how much remains constant.

The first image dates back more than half a century, to an era when everyone was familiar with market traders and the expression ‘shopping mall’ had yet to cross the Atlantic.

Fast forwards to the turn of this century and while the style of the transport has changed, the familiarity remains the same, though it appears to be a traffic warden rather than a police officer on patrol in the foreground.

Even today, when shopping habits nationally have changed, the market continues to be a focus at the heart of the community.

Some details inevitably change, however, and the elevated vantage point used for the two earlier images is no longer available to today’s photographer!
