Milecastle 79, Roman fortification at Port Carlisle, Great Britain
Milecastle 79 is a rectangular Roman fortification near Port Carlisle with stone walls positioned along Hadrian's Wall. The foundations reveal a compact layout with a gateway and chambers designed to shelter a small military garrison.
The outpost was built in the 2nd century as Rome solidified its frontier control in northern Britain and extended its wall toward the Solway Firth. After the Romans withdrew, the structure was abandoned but remained visible in the landscape.
The site reflects how Romans organized frontier control and maintained their presence in this remote region. You can see how soldiers lived and worked at small outposts like this one along the wall.
The site is accessible from Port Carlisle and sits in flat countryside near the border region. The remains are open to the elements, so wear sturdy shoes for uneven ground and be prepared for muddy conditions, especially after rain.
This milecastle was unusual because of its proximity to the coast and may have monitored boat traffic along the waterway. Its location near water made it notably different from most other garrison posts along the wall.
