Erdgas Arena, Multi-purpose arena in Riesa, Germany

The WT Energiesysteme Arena, formerly SACHSENarena, is a multi-purpose hall in Riesa with a main room 112 metres long and 65 metres wide, covering 8,612 square metres. Its variable seating tribunes rise to 27 rows at the ends and 19 rows along the sides, allowing configurations from 1,500 to 9,000 seats or up to 10,000 standing places. A 600-square-metre VIP balcony with three lounges and a press centre adjoin the hall.

The hall was inaugurated on 3 September 1999 as SachsenARENA during the Tag der Sachsen, the Saxon state festival. A sponsorship agreement with the energy supplier VNG AG, concluded in 2002, renamed it erdgasarena; when that contract expired on 28 May 2014, the original name SACHSENarena returned. Since 1 July 2023 it has been called WT Energiesysteme Arena, after the Riesa-based WT Energiesysteme GmbH.

The arena's name has changed with its sponsors: opened in 1999 as SachsenARENA, it became the erdgasarena under VNG AG until that contract expired on 28 May 2014, and since 1 July 2023 it has been the WT Energiesysteme Arena, named after a Riesa-based energy firm. The Dome music show was produced here several times, and public broadcasters stage galas and shows in the hall.

The arena sits in Riesa on the Elbe, within the Dresden–Leipzig–Chemnitz triangle. Five separate large car parks around the building hold about 5,000 vehicles, and 15 articulated lorries can park directly in front. Two bus locks serve coach arrivals, and four lorry entrances allow deliveries up to the stage.

The arena's stage is assembled from 300 platforms of 2 by 1 metres, giving 600 square metres of variable stage area up to 1.60 metres high; the same platforms can be used outdoors. Four truck entrances and a load-bearing floor allow deliveries right up to the stage.
