Local and international artists showcase their talent on the walls, façades, and electrical boxes of Boulogne-sur-Mer. During the Festival de Street Art, new artworks are created — and you can admire them all year round. There’s a city walk divided into five routes that take you past every piece. The starting point is on Rue de l’Amiral Bruix, where you’ll also find the first mural. The total length of the walk is 4.37 km, and it takes about 1 hour and 30 minutes to complete. You can find these walks on this website.
