The Oxygen Greenhouse was placed in between a traffic circle and an urban railway station, on a tiny green spot mostly frequented by dog owners.
People are invited to sit on the sand-filled cushions, take a breathing mask and inhale some fresh air.
Nørrebro is the most densly populated area in Copenhagen. Many people living here are immigrants - the hooka on top of the greenhouse refers to this.
The greenhouse was part of the exhibition "Hot Summer of Urban Farming", initiated by www.publik.dk
