It helps that the city has always been blessed with green space. Around 46% is covered with forest that stretches right into the centre of town. With four landscaped parks and various other green spaces as well, it means that almost all the city's residential areas lie within 300m of a public green space.
Beyond this the city has worked hard to shift its population away from cars. Back in 2007, an ecological zone was created in the city centre, which is now closed for motorised vehicles. In the past five years, these pedestrian areas have been increased by almost 620%. Actions like these, along with a successful bike sharing scheme, have resulted in the city being the only place to be declared the Winner of European Mobility Week Award twice, first in 2003 and again in 2013.
