Hardknott Roman Fort

Hardknott Roman Fort is an archeological site, the remains of the Roman fort Mediobogdum, located on the western side of the challenging Hardknott Pass in the English Lake District. The fort was built between 120 and 138 on a rocky spur, and was initially garrisoned by a detachment of the Cohors IV Delmatarum from the Dalmatian coast. It was abandoned around a decade later, then reoccupied circa 200 and remained in use for much of the next two centuries.

The fort is on land owned by the National Trust, part of the Trust's Wasdale, Eskdale and Duddon property, and is maintained by English Heritage. It is in the civil parish of Eskdale, the unitary authority area of Cumberland, and the ceremonial county of Cumbria.
