Built almost 2,000 years ago by the Roman occupiers of Britain, Hadrian's Wall is one of the most famous and identifiable World Heritage Sites. This is a memoir of two old friends, one American and one British, who reunited to trek the length of the Wall, reminiscing about the past while also expressing fears about the future. This coast-to-coast voyage examines Roman history, drawing parallels between the fall of the Roman Empire and the recent political developments and uncertainties in the United Kingdom and the United States. The authors share their often-humorous encounters with locals they met along the way while hiking in incessant rain.
