Towns and villages within the district are twinned with others on the Continent to bring unison amongst Europe.
Town Twinning was developed in Europe after the Second World War as a way to bring European people into a closer understanding of each other and to promote cross-border projects of mutual benefit.
The idea is to pair towns and cities in different countries with the accent upon fostering human contacts. Twin towns often, but not always, have similar populations and characteristics.
While still more popular as a concept in Europe than elsewhere, the idea has now spread to other continents. In North America it is known as Sister Cities.
Within Europe, town twinning is now supported by the European Union. The support scheme was established in 1989.
