Velodrom, Multi-purpose hall and velodrome in Prenzlauer Berg, Germany.

The Velodrom is a multi-purpose hall with a cycling track in Prenzlauer Berg, set beneath a wide-spanning steel roof measuring 142 meters in diameter. Inside, a 250-meter wooden track runs around the oval center, while tiered seating for up to 12,000 visitors rises all around.

French architect Dominique Perrault won the international competition for the Velodrom with a design presented in 1992, part of Berlin's bid for the 2000 Summer Olympics, which went to Sydney. Construction began in June 1993 on the site of the demolished Werner-Seelenbinder-Halle, and the building was completed in 1996. The first event was the 86th Berlin Six-Day Race from 23 January 1997, with official handover on 5 September 1997.

The annual Six-Day Race brings professional cyclists and a party-like program together, while spectators sit close to the track and experience the mix of sport and entertainment. On other evenings the interior transforms into a concert arena or sports hall, depending on which event is currently running.

The hall sits directly at Landsberger Allee station and is easily reached via the circle line from central Berlin. Visitors should note that seating arrangements vary by event and access is designed to be barrier-free.

The roof is clad in stainless-steel mesh, not wood, and rises only about one metre above a five-metre landscaped mound planted with apple trees. The hall itself is circular with a diameter of 142 metres, and its steel roof spans 115 metres, the largest self-supporting steel roof structure in Europe, carried by 16 reinforced-concrete columns.
