Nachbarschaftsakademie Prinzessinnengärten is a self-organized  open platform for urban and rural knowledge sharing, cultural  practice and activism. It is located within a mobile urban garden in  Kreuzberg Berlin that allows for farming in a city where most  available land is either paved or contaminated. 

The Nachbarschaftsakademie (Neighborhood Academy) began  2015, with the program City Country Land, inviting representatives  of initiatives from New York, Chicago, Madrid, Paris, Hamburg,  Berlin and Brandenburg to work on questions of urban and rural  resilience, commons, land-politics and social housing. Based on  this program we are complementing our learning platform with an  experimental DIY-architecture: Die Laube (The Arbor), and a local  DIY-network to serve as a living academy archive.
