Near the Schottenring underground station you will find the oldest legal sprayer area in Vienna: the Danube Canal. It was legalized in 1994 and offers approximately 480 m² of wall - about 120 metres long on both sides of the canal. But no one has really stuck to this restriction and that's why it's definitely worth going for a long walk along the Danube Canal.
If you like the wild mixture of graffiti, smeared name tags and occasional murals, you will find two interesting areas along the Danube Canal along the U4 subway: the Rossauer Lände (Rossauer Lände station) and the Nussdorfer Lände (Heiligenstadt station). Artists like Skero, Beat and Samba can be found immortalized alongside the water.
In the SprayChilled store near the sprayer area on the Danube Canal there are ongoing street art exhibitions. People can also even visit graffiti courses there and afterwards immortalise themselves on the walls of the Danube Canal: every first Saturday of the month.
