Un Singe En Été

Founded in 2015 by the association Tribu Familia, Un Singe en Été takes place in the grounds of the Château de Mayenne, by the river, on the last weekend of June. The lineup combines independent rock, electro, hip hop and experimental pop with stage performances and street arts, set in a heritage backdrop. Run largely by volunteers, it draws close to 8,000 attendees each year.
