The partnerships of the state capital Mainz are based on long-term contacts and broad engagement from civil society, culture, education, business, and administration. Encounters between citizens, joint projects, and institutional cooperation help to keep relations between the cities alive.

The official establishment of a city partnership in Mainz is based on a decision by the city council. Great importance is attached to achieving the broadest possible consensus in order to anchor the partnerships permanently and independently of changing political majorities.

Town twinning arrangements by the state capital of Mainz are therefore not only an expression of international friendship, but also a contribution to understanding, cooperation, and shared responsibility in Europe and the world.
