Following a course generally easterly, but greatly winding, it passes Harbottle, near which relics of the Stone Age are seen, and Holystone, where it is recorded that Bishop Paulinus baptized a great body of Northumbrians in the year 627 . Several earthworks crown hills above this part of the valley. and at Cartington, Fosson and Whitton are relics of medieval border fortifications . The small town of Rothbury is beautifully situated beneath the rugged Simonside Hills . The river dashes through a narrow gully called the Thrum, and then passes Brink-burn priory, of which the fine Transitional Norman church was restored to use in 18'58, while there are fragments of the monastic buildings . This was an Augustinian foundation of the time of Henry I . The dale continues well wooded and very beautiful until Warkworth is reached, with its fine castle and remarkable hermitage . A short distance below this the Coquet has its mouth in Alnwick Bay (North Sea), with the small port of Amble on the south bank, and Coquet Island a mile out to sea . The river is frequented by sportsmen for salmon and trout fishing No important tributary is received, and the drainage area does not exceed 240 sq. m .
