Copenhagen is a green city well endowed with open spaces. It has an extensive and well-distributed system of parks that act as venues for a wide array of events and urban life. As a supplement to the regular parks, there are a number of congenial public gardens and some cemeteries doubling as parks. It is official municipal policy in Copenhagen that all citizens by 2015 must be able to reach a park or beach on foot in less than 15 minutes.
