The Roskilde Festival Folk High School is closely linked to the world-famous Roskilde Music Festival, which every year temporarily turns this small town on the outskirts of Copenhagen into the fourth- largest city in Denmark. The school is an example of the Danish system of folk high schools, which deliver a “non-formal adult education” following the concept of “lifelong learning”. This system is based on the ideas of 19th-century Danish intellectual N.F.S. Grundtvig, who believed schools should educate their students to be active participants in society. Courses at Roskilde Festival High School last between 4–10 months, with students and teachers living together at the school to achieve total immersion in their education. The Roskilde Festival High School is the first purpose-built school of this type in Denmark in 50 years and aims to further the values of the Roskilde Festival through courses in music, media, leadership, politics, art, architecture, and design.
