The project “United for those in Needs: Learn, Open, Care, Keep – the Museum Mediator as Diversity Integrator” (UNLOCK), financed through the Erasmus Plus  Programme, Key Action, Vocational Education and Training, starts from the role of museums as veritable vectors in societal development, community  catalysers, and their exemplary role in shaping individual and group consciousness. That is why, our final goal is to create the premises for improved museum experiences for persons exposed to various forms of exclusions, whatever the reasons of such attitude.
