War'l Leur (literally "on the ground" in Breton language, as heard "on the area to be danced") is a confederacy of Celtic circles established in late 1967. Other confederacy in Brittany is Kendalc'h. The association gathers a large number of groups of Breton traditional dance which propose shows and animations throughout the Brittany region, in particular in summer, but also elsewhere in France, Europe and abroad.
The federation War'l Leur also aims collecting, studying and transmitting the arts and the popular traditions in Brittany. So it proposes every year internships of dance, music, singings, embroidery, as well as exposures and conferences. It also organizes festivals and parties, in Brittany and elsewhere, including the summer.
