Summary: Melvyn Bragg and his guests discuss Hadrian's Wall, the largest Roman structure and one of the most important archaeological monuments in Britain. It was built across North England in about 122 AD by the Emperor Hadrian and, even after more than a century of excavations, many mysteries still surround it. Did it have a meaningful defensive role or was it mainly a powerful emperor's vanity project? Melvyn Bragg is joined by Greg Woolf, Professor of Ancient History at the University of St Andrews; David Breeze, Former Chief Inspector of Ancient Monuments for Scotland and Visiting Professor of Archaeology at the University of Durham and Lindsay Allason-Jones, Former Reader in Roman Material Culture at the University of Newcastle.
