Adrien Tirtiaux, a young Belgian artist studying in Vienna, wanted to comment on the Biennial. Copying the Biennial work tags, he pointed out to a fire exit at Antrepo for the careful eyes as Alain Posteur. Follow the stairs to heaven, reach the opening, take some fresh air and look at the living city outside. We don't know if the work still works but for your information. Courtesy of the artist.
