La Démence Anniversary Weekend

La Démence is a gay party brand rather than a single event. It started in 1989 as a Sunday party in smaller Belgian towns, moved to Brussels in the 1990s and is now at home at Fuse, the club on Rue Blaes in the Marolles. It runs several times a year, not every month, usually on a Friday or the night before a public holiday. There are three floors: big-room sound on Level 1, deeper and harder on Level 2, pop on Level 3. Nights run into the next morning; in February 2026 Level 2 went until 11am.

The 2026 dates were 20 February, 5 April, 30 April, 24 May (the Pride edition), 25 September and an anniversary weekend opening Friday 30 October, the brand's 37th, spread over three nights into early November. A regular night cost €25, or €20 under 26, and the DJs come from Belgium, France, the Netherlands, Germany, the UK and Romania.

There was no June party on the 2026 calendar we found, so treat this page's June slot as a placeholder and check lademence.com for the real nights. The 2027 dates hadn't been announced when we checked.
