Hadrian's Wall

Built around 120AD, The wall is approximately 70 miles long. Considering its age, it is very well-preserved. It is very difficult to appreciate the vast amount of work involved without physically seeing it.

Hadrian's Wall was a 117 km long defensive wall built from 122 AD under Emperor Hadrian as the northwestern border of the Roman Empire. The wall ran from the Tyne to the Solway Firth, its central section following the natural ridge of the Whin Sill, a hard dolerite geological formation. This location offered Roman troops a tactical advantage: high ground with wide visibility and natural defenses. The wall served to control movement, delay incursions, and demonstrate Roman power.
Here, next to Birdoswald Fort, you'll find the longest remaining section of the historic wall.
