Every October, Brussels becomes the center of Europe’s gay party circuit thanks to La Demence Anniversary Weekend. Spread over three marathon nights, this event attracts thousands of men from across the continent, all heading to the city’s iconic nightclub, Fuse, for one of the most talked-about weekends of the year.
The atmosphere is pure energy. Fuse’s multi-level layout offers huge dance floors, balconies, and darker corners for those who want to explore. Light shows and visuals transform the space, while international DJs keep the music pumping with progressive, tribal, and techno beats. The sound system is massive, designed to drive the crowd well into the morning.
What makes the anniversary weekend special is the scale. Regular La Demence parties already draw a crowd, but the birthday edition is bigger, busier, and even more international. You’ll find groups of friends from Paris, Berlin, Madrid, and London mixing with locals, giving the event a pan-European feel. It’s easy to strike up conversations in line, at the bar, or while catching your breath between sets.
The crowd is mostly men, with a mix of ages, body types, and styles, all united by a love of big-room house and techno. Shirts often come off within minutes of arrival, and the mood shifts from intense dance floor focus to playful socialising as the night stretches on.
La Demence Anniversary Weekend is more than a single party. It’s a ritual for many who return year after year, booking hotels early and planning their October around it. For visitors, it’s the perfect excuse to discover Brussels by day before losing yourself in Fuse’s sprawling, sweaty nights.
