A youth and cultural center in Wels. Most of the walls around the main building are painted. You need a permission. Just ask someone walking around on the property, they will guide you to the right person. Not very good quality, you would not paint there for fame but it's very chilled to paint there. schl8hof.wels.at
You will be able to ask wich wall you can use.
Is this wall still safe to paint?
