In the first programme, Bettany and Ben explore Tintagel Castle and consider the archaeological evidence that it was once the home of the legendary King Arthur. They set out to investigate whether there is any truth in the myth and discover that the site was once linked to the richest trade networks in the world. They also learn that some ancient graffiti could reveal how the legend of Arthur began.

In episode three, we explore the mysteries of Stonehenge, the most famous prehistoric monument in Britain and an icon across the world.
