The aim of the project "International Festival of Children's Rights and Citizenship" is to reaffirm the collective rights of children and adolescents today in Europe and around the world. We conceived this project as a highlight during the 30th anniversary of the International Convention on the Rights of the Child. The main activity of the project is an exchange of children and adolescents, entitled International Festival of Children's Rights and Citizenship. Before the exchange, activities are offered in leisure centers to enhance intercultural group dynamics.
