One of the biggest music festivals in Europe has taken place in Kostrzyn every year since 2004, usually late in July and early August. The event is open (free admittance) and, although it lasts for three days, most of the participants come to town a few days earlier, creating the atmosphere of a gigantic picnic. In addition to the main stage, a smaller one operates, also called “the folk stage”, along with a number of additional, smaller initiatives which enjoy great popularity. For example, the Academy of Finest Arts is an artistic workshop holding art classes, or meetings with people of culture, art, politics, religion, etc. In the several days of the festival, colorful processions of people pass through the town, giving it a specific, festive atmosphere.
