The Fusion Festival is a music and arts festival with a countercultural character. It takes place at a former military airport called Müritz Airpark in Lärz, Mecklenburg-Vorpommern, in northeastern Germany. The festival name is often depicted in Cyrillic letters as Фузион, but pronounced like the English word fusion []. The annual festival was started by the Kulturkosmos organisation in 1997 and is described by the organizers as a place to practice "Holiday Communism" (Ferienkommunismus). It lasts four to six days, usually at the end of June. In 2016, the Fusion Festival event took place from 29 June to 3 July and which has attracted some 70,000 attendees for each year's festival, since the 2013 event, which the comparable American Burning Man event only matched in 2015.
