The parish is also known for its unusual hexagonal
Bewcastle Roman Fort, which has been identified as
Fanum Cocidi; its grassy ramparts can still be seen surrounding the churchyard. The fort was originally built from turf and timber and garrisoned by the First Nervian Cohort of Germans. It was built as an outlying defence of
Hadrian's Wall to the south, to which it was linked by a road direct from the Roman fort of
Banna (Birdoswald) on the wall, and a signal station on Gillalees Beacon between the two. The fort was later rebuilt in stone. Much of the stone was subsequently used to build a
Norman castle within the northern perimeter of the fort. The ruins of
Bewcastle Castle have recently been consolidated by
English Heritage, and are accessible to the public without charge. ==People==
