Grand highline tournament between the towers of the medieval castle of Lassay
The Tournoi des Sangles is one of the most unique events in Mayenne: a highline tournament (slacklining at height) stretched between the towers of a 15th-century medieval castle. The Château de Lassay, an admirably preserved fortress with its eight towers and moats, offers a spectacular and vertiginous setting for this sport, which involves walking, dancing, and performing acrobatic figures on a line stretched more than ten meters high.
The Tournoi des Sangles is produced by the Houle Douce company, based in Marseille, a pioneer in slackline performance in France. Founded by balance and performance enthusiasts, the company has developed a unique artistic language combining sport, aerial dance, and performing arts. The Château de Lassay has become one of their favorite venues for creating shows specifically designed for the site.
The tournament brings together top-level athletes from around the world:
The highlight of the Tournoi des Sangles is the nightly show, an original creation by the Houle Douce company specifically designed for the Château de Lassay. Titled “De la pierre à l'étoile” (From Stone to Star), this show transforms the fortress into an open-air stage:
The tournament takes place over a full week in August, alternating training sessions, highline competitions, and public performances. The days are dedicated to the sporting events between participants, while the evenings of Friday and Saturday welcome the public for the nightly shows. This extended format allows athletes to immerse themselves in the location and create unique performances adapted to the castle's architecture.
From August 9 to 16, 2026, the Château de Lassay hosts the Tournoi des Sangles, a major highline (slackline at height) tournament stretched between the towers of the medieval fortress. Organized by the Marseille-based company Houle Douce, this event combines sport, art, and heritage, in a contemporary version inspired by medieval jousts.
For its 2026 edition, the Tournoi des Sangles will set up highline ropes for a week around and above the Château de Lassay, some connecting emblematic points of the town (town hall, retirement home). A dozen international athletes will compete to music on ropes suspended about ten meters above the ground, over the fortress courtyard.
Designed by the Houle Douce company, the tournament is inspired by medieval jousts and combines the castle's heritage with contemporary performance. The week is punctuated by elimination tournaments and performances, leading up to the final shows where the public is invited to support their champions.
Announced athletes: Louise Lenoble (freestyle highline world champion, France) and Cécilia Stock (freestyle highline world champion, Germany/Italy), Ugo Cavalier (tightrope walker, coordination), Nicolas Pouchard (tightrope walker-musician: saxophone, flute) and Antonin Gavoty (pyrotechnics).
By car: Lassay-les-Châteaux is located in northern Mayenne, about 55 km from Laval via the D162 then D34. The castle is in the town center.
Dates: One week in August (approximately August 9 to 16). Nightly shows on Friday and Saturday evenings at 8:45 PM.
