“The Land is close to the original adventure playgrounds that started in Denmark during the second world war. The first was created by the landscape architect Carl Theodor Sørensen after watching children playing on bombsites, building and demolishing. It opened in Copenhagen in August 1943 and was known as askrammellegepladsen, which translates as “junk playground”. Nothing was static or expensive – it was all wood, rope, empty vehicles, bricks and logs, and the children had the power to create their own world.”
