Dan Snow explores the physical remains of Hadrian’s vast project of 122AD - over 80 Roman miles of wall, turrets and forts, stretching from coast to coast across northern England. Mile after mile of stone marching over the horizon. But why did the Romans go to all this effort? We dig into the key questions: was the wall a barrier or a porous border; a hubristic vanity project or a vital line of defence; who lived on and around the wall; and why has it endured in popular culture for nearly two thousand years, right up to Game of Thrones? He chats to historians Alexandra Croom, Simon Elliot and Rob Collins to learn more. From The Wall: Rome's Great Northern Frontier Best History Documentaries is part of The Little Dot Studios Network.
