Grotenburg-Stadion, Football stadium in Krefeld, Germany

Grotenburg-Stadion is a football ground in the Bockum district of Krefeld, bordered directly by the city zoo. A cantilevered concrete roof carried on a row of columns covers the main stand, its front edge lettered "Grotenburg-Stadion Krefeld"; below it, yellow stairways divide red centre seats from grey-green seats at the ends, and a floodlight pylon stands at the left. Capacity is 34,500, of which 9,943 seats and 4,485 standing places are covered.

Built in 1927, the Grotenburg long held 18,000 spectators. The Neue Tribüne opened on 22 July 1975, when 22,000 saw Bayer 05 Uerdingen beat FK Pirmasens 6:0 and win promotion to the Bundesliga. The Westkurve was raised in 1979 to 28,000; 28,000 attended the 1986 European Cup semi-final against Atlético Madrid (2:3).

The club has played here since 1971, as FC Bayer 05 Uerdingen until 1995 and as KFC Uerdingen 05 since. Locals call the ground "die Grotenburg". Since 2023 the Krefeld Ravens American football team also plays its home games here, and Krefeld Zoo borders the grounds.

The stadium sits in Bockum directly beside Krefeld Zoo, so matchdays bring traffic and parking pressure to the surrounding streets. Standing areas are currently only partly usable, and the ground has been closed for league matches during renovation work, with KFC Uerdingen playing home games elsewhere. Check the current status before travelling.

The Grotenburg was built in 1927, not in the early 20th century, and its record attendance of 28,000 was reached on 16 April 1986 during the European Cup semi-final against Atlético Madrid, which Uerdingen lost 2–3. The stadium has 9,943 covered seats, 4,485 covered standing places and 20,072 uncovered standing places, though the standing areas are currently only partly usable.
