Partenalia is the only no-profit International Association of intermediate local authorities (Nuts III) for inter-territorial cooperation.

It was created in 1993, as a network aiming to enhance the visibility of intermediate local authorities in the process of European integration, and to promote the common policies at the local level.

Today, as an International Association with juridical personality, Partenalia represents the voice of local intermediate authorities in the European arena and offers them a privileged working platform in order to promote innovative initiatives and the interchange of best practices on a transnational scale.
