Berwick-upon-Tweed, (pronounced "Berrick") situated in the county of Northumberland, is the northernmost town in England, situated on the east coast on the mouth of the river Tweed. Although in that region the Tweed forms the border between England and Scotland, and Berwick is located on the northern, Scottish, side, the modern boundary diverts itself around the town to keep it in England. In 1991 the town had a population of 13,500. It is the administrative centre of the borough of Berwick-upon-Tweed.
Berwick is a market town and, if it is taken to include the village of Tweedmouth on the southern bank of the Tweed, a very modest international seaport. For a period of 300 and more years from the mid 11th century the town was an extremely important strategic asset in the wars between England and Scotland. The architecture of the town reflects its past, in particular in having one of the finest remaining defensive walls - albeit one much repaired in the late 18th Century - and in the Barracks buildings. The town proper lies on the north bank and to the north of the River Tweed, and was formerly the county town of Berwickshire.
The town's population in the 2001 Census was 11,665 (including Spittal, Tweedmouth, Ord &c; this within a borough population of 25,949). 59.5% of the population are employed, and 3.6% unemployed. 19% are retired. . Slightly more than 60% of the population is employed in the service sector, including shops, hotels and catering, financial services and most government activity, including health care. About 13% is in manufacturing; 10% in agriculture, and 8% in construction . Some current and recent Berwick economic activities include salmon fishing, shipbuilding, engineering, sawmilling, fertilizer production, and the manufacture of tweed and hosiery.
It is unique for an English town in that its football team Berwick Rangers F.C. plays its matches in the Scottish Football League.
While Northumbrian and Scottish versions of the English language are fairly similar to outsiders, the English spoken in Berwick is recognisably of the Scottish accent.
Berwick's strategic position on the English Scottish border during centuries of war between the two nations, and its relatively great wealth led to a succession of raids, seiges and take-overs. Between 1147 and 1482 the town changed hands between England and Scotland more than thirteen times, and was the location of a number of momentous events in the English-Scottish border wars. In the 13th century Berwick was one of the most wealthy trading ports in Scotland, providing an annual customs value of £2,190, equivalent to a quarter of all customs revenues received north of the border. A contemporary description of the town asserted that 'so populous and of such commercial importance that it might rightly be called another Alexandria, whose riches were the sea and the water its walls .

At war with Russia?
Various proclamations promulgated before 1885 referred to "England, Scotland and the town of Berwick-upon-Tweed". One such was the declaration of war against Russia in 1853, which Queen Victoria signed as "Victoria, Queen of Great Britain, Ireland, Berwick-upon-Tweed and all British Dominions". But when the Treaty of Paris (1856) was signed to conclude the war, "Berwick-upon-Tweed" was missed out. Was it still at war with Russia or not? In 1966 a Soviet official waited upon the Mayor of Berwick, Councillor Robert Knox, and a peace treaty was formally signed. Mr Knox is reputed to have said "Please tell the Russian people that they can sleep peacefully in their beds."
