The OWL ARENA is a multifunctional arena with closable roof accommodating 11.500 visitors, that was built in 1992 with the name "Gerry Weber Stadion". The design engineering which is unique in the whole of Europe allows it to convert the Stadium within 90 seconds into a venue independent of weather.
Seasonal highlight is theATP lawn tennis tournament, the TERRA WORTMANN OPEN. Since its premiere in 1993, the Event evolved into one of the most successful ATP tournaments in Europe. TV audience rates and total numbers of viewers (over 100,000 spectators each year) remain unequalled in Germany. Further national and international sports events – Davis-Cup-home matches, handball major events, ice skating shows and the German Volleyball Cup finals– alternate with high-class concert events.
Over the past years Luciano Pavarotti, Placido Domingo, Lionel Richie, Eros Ramazzotti, Bryan Adams, Rod Stewart, Peter Maffay and Elton John and others performed here in front of an enthusiastic audience. In addition, the OWL ARENA is superbly suited for product presentations and company incentives. For example, vehicle presentations of the companies MAN and Volvo, and also the 100th anniversary of the Storck company have been held in the arena.
