Vauban District Green City

Every building in Vauban has solar panels on its roof. It’s not surprising that Vauban is the greenest area of the greenest city, Freiburg, in the greenest province, Baden-Württemberg, in Germany. Freiburg, a city of about 220,000 people and 155 km2, is already known as an eco-city with the Green Party having the strongest presence there of anywhere in the country.
