The Ruhrtriennale is an annual music and arts festival in the northwestern area of Germany which runs between mid-August and mid-October. It was founded in 2002 by the government of North Rhine-Westphalia with Gerard Mortier, the impresario and former artistic director of the Salzburg Festival, as its founding director. The festival is organized into three year cycles, each with its own theme and under different artistic directors.
Each yearly festival comprises 80 performances of 30 productions. Its central feature are the Kreationen (creations) – interdisciplinary productions uniting contemporary developments in fine art, pop, jazz and concert music. Another continuous element is the concert series, Century of Song, dedicated to the art of songwriting. The locations of the Ruhrtriennale are industrial heritage sites of the river Ruhr, which have been transformed to into venues for music, theatre, literature and dance. The festival's main hall is the Jahrhunderthalle, a former early-20th-century power station in Bochum. Other locations include the Zeche Zollverein colliery in Essen, the Landschaftspark Duisburg-Nord and the Maschinenhalle Zweckel in Gladbeck.
Amongst the artists who have appeared at the festival are Ariane Mnouchkine, Peter Brook, Bill Viola, Patrice Chéreau, Ilya Kabakov, Peter Sellars, Christian Boltanski, Bill Frisell, Patti Smith, Elvis Costello, Akram Khan, Cecilia Bartoli and Thomas Hampson.
