Nomadisch Grun (Nomadic Green), the brainchild of Robert Shaw and Marco Clausen, leased a patch of wasteland in order to realize their vision of a green space in the heart of the community. The idea was born out of a trip Robert made to Cuba, where he saw similar spaces where people would gather to work, learn and relax. In 2012 the Prinzessinnengarten faced the threat of closure. The Berlin Property Fund was tasked by the Berlin Senate to find a buyer for the city-owned plot of land where the garden is based. Nomadisch Grun sought to engage with the Berlin Senate to discuss the future of the project and collected 30,000 signatures on a petition to keep the Prinzessinnengarten open. Thankfully, in this instance the Senate saw sense. On 14 December 2012, The Berlin Property Fund agreed to return the land to the borough and the threat of closure was averted.
