Dubois-Arena, Outdoor amphitheater in Borbeck district, Essen, Germany

The Dubois-Arena is an open-air venue in the Borbecke valley below Schloss Borbeck in Essen-Borbeck. It consists of a surviving semicircular concrete grandstand facing a covered music pavilion, rebuilt as an amphitheatre and reopened in 1996. It holds about 1,800 spectators.

The Dubois-Arena opened on 2 August 1950, built by members of the Essen Boxing Club Dubois, which Ernst Dubois had founded in 1920. Up to 25,000 spectators attended amateur and professional bouts; in 1957 Archie Moore fought Hans Kalbfell with Max Schmeling as referee. After boxing declined, the site was rebuilt and reopened in 1996 as an amphitheatre.

The name comes from the Dubois Boxing Club that shaped the venue for decades. Today, visitors and event organizers experience it primarily as a place for outdoor performances and gatherings.

The arena sits within Borbeck Castle Park with easy access via walking paths and multiple entrances throughout the area. Visitors should prepare for outdoor conditions and bring appropriate clothing for changing weather during performances.

The grounds remained a gathering point for boxing enthusiasts and athletes for many years before shifting to a broader cultural purpose. This sporting heritage is now visible mainly through the structure itself and the name, while daily activity is defined by diverse cultural programming.
