RWR3 - more history

A detour north to see the very fine Hermitage Castle, "a lonely spot, and the sight of the awesome castle ruin only heightens the sense of foreboding.  Hermitage Castle has inspired local legends but its history of torture, treason and romantic trysts is more than colourful enough".  
Then our route took us round Kielder Water and on to Bellingham for the night.
