Arts'R'Public is an Euro-Mediterranean laboratory for arts in public spaces, designed in a dual approach, crossing networks and strengthening international careers of emerging artists with central dimension for the development and integration of new audiences in their artistic projects. Around a partnership consisting of professionals of arts in public spaces from four twinned cities (Marseille, Hamburg, Marrakech and Genoa), 16 international artists will participate in a path punctuated by training, mediation, design and development of personal artistic projects. Over the steps, they will have the opportunity to acquire specific skills to create in public spaces and experiment new approaches to engage young NEET (Not in Education, Employment or Training) in their projects. During art workshops conducted in priority areas, they will explore with these young specificities of arts in public spaces and get prepared for the crossed residences. Each partner will host an intercultural collective composed of 4 artists and 8 young Moroccan, German, French and Italian for the production of a creation that will be presented in an international of street arts festival, in an urban area and a rural area where the cultural offer is rare. From these experiences, the artists will draft a personal project that takes into account the interaction with the public far from the cultural offer. For the final event of Arts'R'Public, their projects will be presented to a panel of professionals from the artistic and creative sectors. A seminar and conference will capitalize the results and the topics of Arts'R'Public for the emergence of new contributions and ideas to develop and engage new audiences, train new generations of creators in public spaces and to develop artistic exchanges in the Euro-Mediterranean zone.
