Stadtzeichen "Water" at Fontänengasse is the entrance to Creative Quarter North. Only a few steps away from this first landmark, at the mouth of Kasteienstraße, you'll find the next one - "Coal". It states the outstanding importance of this raw material for the city which has had the most coal mines in Europe, and so, up to the mid 1960s, mining industry was the most important economic sector in Essen. Please note the high class stickers and just recently the installations that use the polished face of that obelisk as a showcase for street art
