Geheimzinnig Open Air is an annual festival that typically takes place at the end of the summer. Their locations vary from the middle of a cornfield to a genuine festival ground at De Konijnenweide in Antwerp. With a major focus on top-notch sound, lighting, local food, reputable DJs, and overall experience, Geheimzinnig has firmly established itself on many people's calendars. Good food, superb DJs, and insane production—wouldn't you want to mark it in your agenda?

Once a year Geheimzinnig strikes down at a castle in or around Antwerp city. After two memorable events that brought irresistible beats to the captivating surroundings of Kasteel Hof Ter Linden, they are changing venues this year. In 2024, they will be landing at Kasteel Sterckshof in the Rivierenhof park for what promises to be a fantastic kickoff to the well-filled Belgian festival season.

What started in obscure venues has now grown out to become Geheimzinnig's trademark. More often than not, these notorious club nights take place in the well-known club "Ampere" now called "Kasko". Most recent editions invited renowned artists like David Vunk, Demuja, Hunee, San Soda and Kléo.
