Town twinning is the concept of creating a partnership between cities. The main goal for the cities is to work together in cultural and economical sectors as well as to inform about city structure related issues. Most twin town arrangements are between cities in different countries that face similar social, economical and political situations or perhaps share historical links.
The first official partnership involving a German town was formed in the year nineteen-thirty between Wiesbaden and Klagenfurt in Austria. Locations in the Ruhr Metropolis have twinned with more than 200 national (from GDR days) and international towns.
