Club Hölle logo.
Club Hölle was a nightclub on the outskirts of Berlin, Germany, which was owned and operated by Rolf Hirschmüller, the leader of Berlin chapter of the Ragnarok Disciples biker gang. Set inside a repurposed nuclear power plant down the road from a gas station and diner, the club features a prominent dance floor with dazzling light displays, several makeshift bar areas, outdoor areas, as well as tech and staff rooms. The concrete exterior is adorned with artistic murals. A section of the facility also houses a hangout for the Berlin chapter of the Ragnarok Disciples.
After an incident when multiple agents of the International Contract Agency were found dead inside of it, the club shut down for a while, only to later open again under the name "Club Boom."
