Explorer Tom Hadrian's Wall runs across northern England so far that Tom tried to count its stones and ran out of afternoon. It was begun on Emperor Hadrian's orders after his visit in AD 122, marking the north-western frontier of the Roman Empire. The surviving stretches cross towns, fields and crags; no single viewpoint can tell the whole story. The frontier ran about seventy-three miles, from Wallsend on the Tyne to Bowness-on-Solway. Roman soldiers built it with milecastles at roughly every Roman mile and smaller turrets between them; forts were later added along the line. The wall controlled movement and displayed imperial power, but the forts also held ordinary lives: meals, letters, repairs and long watches in bad weather. Tom would have asked for a post by the fire. Rome might have assigned him the coldest turret. A good way to understand the scale is to pair a stretch of open wall with a fort such as Housesteads or Birdoswald. On the central crags, stone rises and falls with the ridgeline; elsewhere the frontier is quieter, sometimes a low trace in a field. The changing landscape is part of the monument, so let your walk follow a manageable section rather than trying to conquer the full line at once. Walking beside the wall on public paths is free, while some forts and museums charge admission. Much of the land is privately owned, so keep to rights of way and never climb on the ancient masonry. Weather can be fierce and paths uneven; carry a map and layers. Every surviving stretch is a small piece of a much bigger border.
