Tony and the Team visit Newmarket, the birthplace of horseracing, in search of the earliest archaeological traces of the sport of kings. They dig in the heart of the historic town, in search of the remains of King Charles II's racing stables arguably the world's first stables dedicated for racing.

It's the last chance to work here, as construction is about to begin on a multimillionpound National Horseracing Museum.

From the start of the dig, the challenge for the Team is to find evidence that will enable them to distinguish a racing stable from an 'ordinary' royal stable block. The pressure's on for team leader Jackie McKinley to deliver the key small find or insight. With a thick layer of concrete lying over the site, it's not an easy task.

And across the road from the stables site, there's a second area to explore: King Charles II's 17thcentury Newmarket palace. To add to the excitement, there's the prospect of Tony Robinson attempting to ride a mechanical racehorse, and a team visit to the racecourse on Ladies Day.
