About sixteen years ago, two skaters found a plot of fallow land in Hanover-Linden’s industrial area. They start to clean up and build a small skate park. In 2009, they form an association, negotiate an interim use contract with the owner together with the city council’s support, and reach a lease agreement for one euro per year, which is still valid today. In 2013, another association is created: Platzprojekt aims to create a space for initiatives, a place for self-help, for mutual support offering knowledge, tools, and craftsmanship. Research funds and state subsidies enable the establishment of long-term participation structures for young people who want to discuss their cities in self-organized spaces and actively shape them.
