The 2026 edition will take place from 1-4 July and continues the proven four-day format with multiple stages and expanded festival infrastructure.

About

Open’er Festival started in 2002 in Warsaw as Open Air Festival and quickly grew from a new concert project into one of the most important music festivals in Poland. Since the beginning, it has been organized by Alter Art, and the brand developed through a consistent combination of international headliners with alternative, electronic, hip-hop and pop artists. A major turning point came when the festival became permanently linked with the Tricity area and the Gdynia-Kosakowo Airport site, where Open’er expanded into a full-scale four-day open-air festival with multiple stages, camping and extensive infrastructure. In the organizer’s materials, the event is presented as the largest and most diverse festival in Poland, and its format includes not only concerts but also additional cultural and entertainment activities. Open’er’s music profile has long been built around a broad mix of genres, from rock, pop and indie to hip-hop, electronic music and special projects. Because of that, the festival attracts both audiences focused on the biggest global names and people looking for a more varied, curated festival experience. That balance is one of the main reasons why Open’er has become a brand recognized not only in Poland, but also more broadly across the European festival market. In practice, Open’er now functions as a large temporary festival town built on the airport grounds and serving a very large audience from Poland and abroad. Yourope states that the event includes seven stages, a campsite and attendance reaching 90,000 across four days, while the record-breaking 2018 edition drew 140,000 visitors. The 2026 edition will take place from 1 to 4 July at Gdynia-Kosakowo Airport and will continue the same proven format. The official lineup includes Florence + The Machine, The xx, Calvin Harris, Nick Cave & The Bad Seeds, The Cure, Jennie, Halsey, David Byrne, Martin Garrix, Oki, Sobel and Vito Bambino, which clearly reflects Open’er’s typical balance between global headliners and strong Polish acts.

Event Character

Open’er Festival is aimed at people who want to see major global names, but also expect a lineup broader than a classic single-genre festival. Its strength lies in variety, because alongside headline acts it features alternative, rap, electronic, pop and indie artists, with the programme spread across several stages. It is a festival with European-scale ambition, strongly focused on the overall experience, which means not only concerts, but also infrastructure, camping, additional activities and the atmosphere of a large summer festival town.

History & Evolution

The history of Open’er began in 2002 in Warsaw, when the event still operated under the name Open Air Festival. Over the following years, the festival grew rapidly, expanded in scale and strengthened its position as an event increasingly able to compete with the biggest brands of the European festival season. A key stage of that development was the long-term move to Gdynia and the airport site in Kosakowo, where Open’er developed its full multi-day format with multiple stages, camping and broad visitor infrastructure. With time, the brand came to be seen not only as a major Polish festival, but as an event with established international recognition, reinforced by industry awards and distinctions.

Cities & Locations

Open’er Festival was not always connected with the Tricity area, because its origins go back to Warsaw. Today, the festival is permanently associated with Gdynia-Kosakowo, more specifically with the airport grounds, which make it possible to stage a large multi-stage open-air event. That location has become part of Open’er’s identity, combining a large festival format with a coastal setting and broad accommodation and transport support.
