Please note: This is not a legal wall - It's an open air graffiti gallery!!! Hafendampf is an annual graffiti jam in Essen, which was born 2013. It was named after the location where it takes place traditionally - Essen's little known city port. On the 1st and 2nd of September 2018 the graffity community of North Rhine Westfalia and friends have met in Essen Frilledorf at Franz Fischer Weg for one more spray weekend.
