Illegal rave at Belgian military base ends in €78,635 fines and jail time

A secret illegal rave at a Belgian military base seemed like the perfect party—until authorities shut it down, arrested dozens, and the organisers were ordered to pay €78,635 in damages along with jail time.

Authorities weren’t about to take any chances. Realising how dangerous the situation was, they quickly declared an emergency, called in extra help from Dutch police, and shut it down. Around a dozen people were arrested, and all the equipment was seized.

Fast forward to 2025, and the organisers are facing some serious consequences. A Belgian court has ordered them to pay €78,635 in damages to the Ministry of Defence. One of them got a year in prison, two others received suspended sentences of up to ten months, and another was sentenced to 100 hours of community service. Even the people who provided the sound system weren’t spared—some were given community service, while others ended up with jail time.

This wasn’t even the first time something like this happened. Just a few months earlier, another illegal rave on a military base drew somewhere between 10,000 and 15,000 people. That time, authorities couldn’t immediately break it up because the crowd was just too big. Instead, they kept watch and checked people as they left.

Underground raves have always had that rebellious appeal. The secrecy, the freedom, the music that keeps going until sunrise—it’s easy to see why people love them. But there’s a fine line between thrilling and reckless. Throwing a party in an active military zone, with actual unexploded bombs around, is definitely on the reckless side. And this case makes it clear that the legal system isn’t letting these things slide. If you’re going to throw a rave, it’s probably best to do it somewhere that doesn’t come with a risk of prison time and a six-figure fine.
