The environmental organization Dodo has built an interesting urban farming laboratory called Turntable on top of an old train turntable in Pasila, Helsinki. The Turntable has a greenhouse, an urban farm, a cafe and even a bouldering wall. The Turntable hosts all sorts of open events from urban farming workshops to punk concerts. Places like this really make cities worth living in. Let’s hope the city is clever enough to not destroy it when central Pasila is redeveloped in the near future.
