Nice Hall.Collect your cans.Enough space.
Confirmation from 2015 derwesten.de/staedte/gladbeck/der-graffiti-freigeist-von-gladbeck-aimp-id10922508.html I don't know if the location on the map is correct, but you should find it by asking around.
On the map you cannot see directly that the legal wall is inside of the tunnel. Just go down the stairs and there it is.
Is this wall still safe to paint?
