In the late nineteen-eighties the idea was born of a self-sufficient and self-governed ecovillage. The founding members moved into the "project center" in Groß Chüden from where they launched the ecovillage in Poppau. It is called Sieben Linden which is Seven Linden Trees in English. Since 1997, Sieben Linden has been growing bigger and bigger. So far, 100 adults and 40 children have settled here, building and living as a community.
