I went one of the organized tours of Christiania today. It was lead by Asterix who has lived there since the 1970, except for a period of 12 years when he moved away. It was fascinating to get a more in-depth look at Christiania. I really did not understand it well before then.
Asterix was kind enough to introduce me to a lady who built her own ecological home in Christiania. I hope to meet and interview her, fingers crossed.
