In the location's words:

The MS Treue is an old concrete ship that has been converted into a club. Our night program consists mostly of electronic parties.
The MS Treue sees itself as a place for open-minded people.
Prejudice, racism, sexism and homophobia have no place with us.
Also brands like Thor Steinar, Yakuza and similar are not tolerated here.
A place to have fun without having to pretend, to dance in a relaxed way and maybe drink a beer or Pfeffi too much!
Cheers!
