What is special

The part that makes it specific.

01

The place changes

Open'er's setting, a decommissioned military airfield near Gdynia, gives it space for a sprawling multi-stage layout uncommon among European festivals, supporting eclectic four-day lineups that mix major international headliners across indie, rock, hip-hop, electronic and pop genres rather than committing to one scene

02

The mystery stays covered

Its coastal location near Gdynia and the wider Tricity area (Gdansk, Sopot, Gdynia) lets attendees combine festival days with Baltic beach time, distinguishing it from inland Polish festivals

03

The city starts moving

Since its 2002 founding under Heineken sponsorship, it has built a reputation, at least by general repute, as one of Poland's most internationally oriented festival bookings alongside Orange Warsaw
