Everybody wants to be an urban climber! We are taking the excitement of conquering mountain tops to blocks of flats, skyscrapers and other buildings in Poznań, over to stairways and passageways. For one day, various buildings that are usually locked from the inside will be made available by their residents, and the view from their tops will be democratised. The new arena for your sporting effort will be made of private balconies and rooftops: the PRIV Crown of Poznań.
