The city of Jean-Jacques Rousseau celebrates music on June 21st
Montmorency, a town of art and history in the Val-d'Oise intimately linked to Jean-Jacques Rousseau who stayed there for a long time, celebrates the Fête de la Musique every June 21st in an exceptional historical and natural setting. The medieval alleys, the Saint-Martin collegiate church, and the town's flowery gardens provide an incomparable backdrop for the free concerts that liven up the summer solstice evening.
Every June 21st, Montmorency celebrates the Fête de la Musique in a historical and natural setting that gives it a unique atmosphere in Île-de-France. Perched on a plateau overlooking the plain, this town of art and history in the Val-d'Oise is surrounded by the majestic forest of Montmorency and retains an intact medieval charm in its cobbled streets and half-timbered houses.
It is impossible to mention Montmorency without mentioning Jean-Jacques Rousseau, who stayed there from 1756 to 1762 and wrote his major works there — Julie, or the New Heloise, The Social Contract, and Emile, or On Education. The Enlightenment philosopher was himself a passionate music lover and a composer in his spare time; he notably wrote The Village Soothsayer, an opera-comique that was very successful in the 18th century. The Fête de la Musique in Montmorency thus fits into a philosophical and musical tradition rooted in the very identity of the town.
The Saint-Martin collegiate church of Montmorency, a remarkable Flamboyant Gothic building from the 16th century, is one of the town's architectural jewels. During the Fête de la Musique, this church can host concerts of sacred or classical music that benefit from the exceptional natural acoustics of the place. The collégiale square and the surrounding alleys host more popular and festive concerts.
The Fête de la Musique in Montmorency offers a varied program adapted to this particular context:
Jean-Jacques Rousseau's House, a museum dedicated to the philosopher's life and work in Montmorency, is a major cultural attraction. During the Fête de la Musique, the museum may organize special events related to Rousseau's passion for music, offering visitors an original and scholarly approach to 18th-century music.
The Fête de la Musique in Montmorency is completely free and accessible to all. The open-air concerts, in the enchanting setting of the medieval old town and at the foot of the chestnut forest, offer an unforgettable musical and visual experience that attracts residents and visitors from all over the Paris region every year.
The 2026 Fête de la Musique in Montmorency will take place on Sunday, June 21st, in the historic center and public spaces of the city of Rousseau. Free concerts combining classical music, jazz, and contemporary music in an exceptional medieval setting. Program to be announced in spring 2026.
Montmorency will once again host its Fête de la Musique on Sunday, June 21, 2026, in its exceptional historic center. Free concerts in the Saint-Martin collegiate church, on the medieval squares, and in the picturesque streets of the town will liven up the evening. The program will be unveiled in spring 2026.
