Bewcastle is a large civil parish in the Cumberland unitary authority area of Cumbria, England.

The sundial on its surface is the oldest in Britain,[citation needed] divided into the four 'tides' which governed the working day in medieval times.

"[4] A reconstruction of the whole cross is located in the churchyard of St Mary's neo-Romanesque Church at Wreay near Carlisle, but this differs in style and detail from the original.

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 ruins of Bewcastle Castle have recently been consolidated by English Heritage, and are accessible to the public without charge.
