Luna Luna (1987 exhibition)

Luna Luna was an open-air museum and amusement park in Hamburg, West Germany that ran from June 4 to August 31, 1987; it was rediscovered and relaunched as a touring exhibition in 2023. Curated by Austrian artist André Heller, it was an attempt to "create a travelling terrain of modern art, that in the centuries-old principle of the fairground involves people of all ages and educational levels in playful acts".
