Milecastle 18, Roman fortification at East Wallhouses, Northumberland, England.
Milecastle 18 is a small Roman military fort in Northumberland that was part of a chain of fortifications along the northern frontier. The site preserves the foundation platform of the original structure, which you can walk around and examine for evidence of its layout and construction.
The fort was built in the early 2nd century during the reign of Emperor Hadrian as part of a frontier defense system. It served its purpose for centuries before being abandoned when Roman forces withdrew from Britain.

The site sits in open countryside and is accessible via quiet country roads and footpaths in the area. Information panels on location help explain what you are seeing among the surviving remains.
