Trébeurden’s 13 July celebration combines concerts, fireworks and a DJ set, with free entry from 7 p.m. at the Castel site. The musical programme is strongly rooted in Breton and Celtic sound. Fred Guichen and Jean-Pierre Riou bring accordion and guitar into dialogue across Scottish, Irish and Breton traditions, while Startijenn carries Breton dance music toward a trad, rock and folk setting. Food service is announced on site, keeping the evening in the format of a public summer gathering rather than a seated concert. The row is therefore classified as live culture, local festivity and traditional music.
