Antaris Project

33 Years of Psytrance on the Gollenberg

The Antaris Project is among Europe's oldest and most influential Psytrance festivals. Founded in 1993 by Uwe Siebert, the festival quickly established itself as a central meeting point for the international Goa and Psytrance scene. For years, the venue has been the Gollenberg airfield in Stölln (Gollenberg municipality, Havelland district) — the world's oldest airfield, from which Otto Lilienthal undertook his first documented flight attempts in 1894. The vast field with a view of the Gollenberg serves as the backdrop for a festival with up to 10,000 attendees.

2025 Pause to Commemorate Uwe Siebert

Uwe Siebert, the festival's founder and a defining personality, passed away in March 2025. The team subsequently decided against holding an edition in 2025, describing it as 'not a farewell, but a necessary pause to create space for processing, realignment, and inspiration.' The Antaris website has since dedicated its homepage to a tribute to Siebert's mission: 'For Friendship, Peace, and Freedom.'

2026 Comeback: The 'Last Gathering'

In 2026, the team is planning the comeback — announced as the 'last gathering' and 'the conclusion of a chapter in Uwe's spirit.' The upcoming edition thus combines grief and new beginnings: a festival that honors the founder, places the values of 'Heart, Freedom, Peace, and Friendship' at its core, and offers the international Psytrance community a final shared date on the Gollenberg. The exact date, lineup, and tickets will be released gradually in 2026 on the official website.

Multiple Floors Between Psy and Goa Trance

Antaris traditionally lasts several days (often four days from Thursday to Sunday in the past), with multiple floors: the Mainfloor for Psytrance, a Chill Floor for Ambient and Downtempo, and a Dark Floor for Hi-Tech and Darkpsy. Decorations, light installations, and an international pool of artists characterize the event. Camping, food trucks, yoga spaces, and workshops are part of the concept.

Stölln and the Gollenberg in Havelland

Stölln is a district of the Gollenberg municipality in the Havelland district — a rural region northwest of Berlin. The Gollenberg, at 108 meters high, was ideal for Lilienthal's flight attempts at the end of the 19th century. Today, the decommissioned IL-62 'Lady Agnes' stands here as a monument — and once a summer, the Antaris camp with thousands of festival guests.
