"This sprawling 19th-century former gasworks complex west of the Canal Ring was a polluted site for decades after its closing in the mid-1960s. It was cleaned up and reopened in 2003 as a park, and its architecturally significant red-brick buildings were turned into cultural venues, restaurants, bars, nightclubs, and shops. The Gashouder, a massive circular structure measuring more than 27,000 square feet, hosts mainly techno parties, while the nearby North Sea Jazz Club is an intimate space for live jazz performances. You’ll also find TonTon Club, a restaurant and arcade with video games, air hockey, and table tennis; Pacific Parc, a café with live rock music and DJs; and a three-screen art-house cinema."
