The Zénith de Lille (still known as Zénith Arena) is a multi-purpose indoor arena in Lille, France. Imagined by the Dutch architect Rem Koolhaas with Cecil Balmond and inaugurated in 1994, the Zénith Arena is a part of the cultural complex Lille Grand Palais which includes two other spaces: a Congress Center and Exhibition halls.
