If you think of smoking chimneys when you think of the city in the Revier, you will be pleasantly surprised. The Ruhr metropolis is the greenest city in North Rhine-Westphalia, older than Berlin, Dresden or Munich and was even the European Capital of Culture in 2010. If you stroll through the city, you will not only discover the UNESCO World Heritage Zeche Zollverein, but also one of the most beautiful opera houses in Germany, an underground theatre, the Unperfekthaus or the Phanomania experience field. The tourist city map contains all the important sights, an overview map around Essen on a scale of 1:200,000, an enlargement of the city center on a scale of 1:10,000 and a street directory for quick orientation.
