Hadrian's Wall stretches from coast to coast along what was once the border between England and Scotland. It is the only long distance walk in the world located exclusively within an UNESCO Heritage Site.

Walk along the path of the ancient Romans with Bob and learn about Hadrian - his power, passions and vices - and through this get a vivid picture and understanding of the Romans and their Empire.
