Berwick-upon-Tweed

Although Berwick-upon-Tweed now lies just inside the border of England, historians estimate that it has changed hands between the Scots and the English 14 times. An interesting quirk of history relating to this is that, due to a border dispute while Britain was fighting the Crimean War in the 1850s, Berwick-upon-Tweed was excluded from the official peace treaty in 1856. It thus technically remained at war with Russia until the 1960s, when the Soviets sent a representative to sign a treaty with the town mayor.
