In 1943, Carl T. Sørensen proposed the first Adventure Playground in Emdrup, Denmark. The idea was simple but radical: provide an uncontrolled space for children to do whatever they want; a landscape “in which children could create and shape, dream and imagine a reality” in the city. In 1969, Paulo Freire wrote Pedagogy of the Oppressed, arguing that for education to be truly liberating the student must play a self determined role in assembling knowledge as a “practice of freedom”.
