Something About Hadrian's Wall No Longer Makes Sense

For 175 years every guidebook, museum board and school textbook has told you the Romans built Hadrian's Wall from west to east. Then in 2009 a team from Newcastle University started pulling mortar samples from the stone itself, and the dates came back the wrong way round. So why would the Romans have started building at what we all assumed was the end? In this video: • How John Collingwood Bruce's 1849 map fixed the "west to east" story for good • Henry MacLauchlan's 1850s survey and the wall that kept changing its mind • Why the Vallum earthwork was dug, then almost immediately filled back in • The 2013 Archaeometry mortar-dating study that reversed the construction order • How the South Shields supply depot and the River Irthing stone-to-turf switch back up the reversal • Why the forts, the Antonine Wall and the Vindolanda tablets suggest the whole frontier concept kept failing and changing Chapters: 0:00 The direction everyone assumed 3:20 Building Hadrian's Wall recap 6:40 Cracks in the story 10:05 The Vallum's secret 13:15 The direction problem 16:30 Mortar samples rewrite history 19:45 South Shields evidence 23:00 A wall that kept changing 26:15 The palimpsest revealed Sources and accuracy: this video draws on Henry MacLauchlan's 1858 survey report, Eric Birley's 1936 Birdoswald excavation report, the 2013 Archaeometry paper from Dr Rob Collins's team at Newcastle University, David Breeze and Brian Dobson's Hadrian's Wall (2000), W. S. Hanson's 1986 analysis of the Antonine Wall, the Vindolanda writing tablets held at the British Museum, and Historic England's 2009-2017 LiDAR surveys.
