Milecastle 30, Roman fortification on Hadrian's Wall, Northumberland, England.
Milecastle 30 is a small Roman fortification on Hadrian's Wall in Northumberland that served as a checkpoint for soldiers on patrol. The ruins still show foundation walls and gate passages that mark where soldiers once guarded this section of the frontier.
This fortification was built in the 2nd century to strengthen Rome's northern frontier in Britain. It was part of a connected system of watchtowers and forts that stretched across the region.
This fortification demonstrates Roman military engineering through its long-axis design, featuring two gateways and barracks that accommodated between twenty and thirty auxiliary soldiers.
The site sits along the Hadrian's Wall Path National Trail, a walking route that makes the ruins easy to reach. You can view the remains from the B6318 road, which runs beside the site.
At this location, the wall transitions between narrower and broader stone foundations, revealing different building phases. This shift allows visitors to see how the fortifications changed and improved over time.
