Steel is the formative element of the artworks created by ODIOUS. The six-member group of Berlin artists, which formed in 1982 at Berlin University of the Arts, has left its traces all over the Natur-Park Südgelände, especially in the "Giardino Segreto". As well as many abstract steel sculptures, they also built the 600-metre-long steel walkway that leads through the nature conservation area.

The monumentality and materials of artworks by Odious tie in with the site’s former industrial function and rusting relics of that period and perfectly correspond with its exuberantly proliferate wild nature, giving the park its unique and fascinating character as an ‘enchanted place’.
