Gaudiopolis or the City of Joy was a children’s republic founded by Lutheran pastor Gábor Sztehlo in Budapest after WWII. Gaudiopolis was the home of several hundreds of severely traumatized orphaned and homeless children. The City of Joy not only gave them shelter but also the opportunity „to remove social barriers and become autonomous, self-confident adults, who strive for self-awareness and are capable of self-criticism, are skilled and educated”. Between 1945 and 1949, the period of highs hopes and grave disillusionment, it seemed possible to create a new, free and democratic world. The exhibition presents the history of Gaudiopolis and other similar projects launched by enthusiastic, courageous and persevering individuals and groups who believed in a better and more just society, and who wanted to renew the political and cultural life in the country, reform education and build a new country – somewhere in Europe.
