C12

C12 lives in the Galerie Horta, an underground gallery connected to Brussels Central Station, in a space with Art Nouveau credentials most clubs would kill for. Bruzz was calling it the night owls' new favourite in December 2018, and Vice wrote about the double life of a place that clubbers dance in and then clean up. The Deep in House collective runs it as a multidisciplinary platform for club nights, concerts, installations and exhibitions, and there is a record label attached. It does not publish a capacity. Doors are at 23:00, and the rule on photos and flash is strict. It offered a summer pass in 2026 giving unlimited entry from June to October for 50 euros, which is a thoughtful way to build a crowd. The Brussels Times has called it one of the largest nightclubs in the city and reported that it is planning a 24-hour New Year party, while warning of recent club closures across the capital. The November 2026 listings run from Objekt to hard dance nights, so check who is on.
