River Aln
The River Aln runs through Northumberland from the Cheviots to the North Sea, giving a name to the county town, Alnwick, and to Alnham in the hills at its source and Alnmouth at its mouth.
For part of its route, directly upstream of Alnwick, the river flows through Hulne Park.
History
The Aln is first mentioned in the Geographia of Ptolemy, a 2nd Century AD Roman cartographer. He refers to it as the River Alaunos or Alaunus,[1] on which seems to be situated the town of 'Alauna'.[2] This can speculatively be identified as the Roman fort at Learchild, where the Devil's Causeway crosses the river.
The Aln is a relatively small river but has been important through history as one of the boundaries along which English and Scottish troops marching to war had to cross; for that reason, it was at times heavily defended. For example, the river flows past Learchild Roman Fort and, more significantly, Alnwick Castle which was built for this purpose.
In two battles at Alnwick the river was a significant element: the first in the Battle of Alnwick of 1093 between Malcolm III of Scotland and Robert de Mowbray; the second in 1174 between William I of Scotland and Ranulf de Glanville.
The Synod of Twyford took place by the river according to the Venerable Bede, who describes it as Adtwifyrdi. He describe the meeting of river and tributary at the mouth of the River Aln.
Non-Tidal Ecology
The river has a good run of sea trout and salmon, as well as a population of resident brown trout. Public fishing is controlled by the Aln Anglers' Association.[3] The Aln also has a resident population of otters.[4] Grey heron, barn owls, kestrels and buzzards can be observed hunting along the banks of the river.
Tidal ecology
Part of the estuary is designated a Site of Special Scientific Interest,[5] and the river below Lesbury footbridge (the normal tidal limit, except on high springs and in surge events) was made a marine conservation zone in 2013.[6] large groups of lapwings, oyster catchers and curlews can often be seen. In smaller numbers are mallards, shelducks, grey herons, cormorants, greylag geese, Canada geese, swans and the occasional family of goosanders. Less often spotted are barn owls, kestrels, avocets and little egrets. Further down the tidal zone a visitor will often see Sandwich terns and common terns, as well as a variety of gulls and smaller waders including redshanks, greenshanks, turnstones, ringed plovers, pied wagtails, and other sandpipers.
