Arena Loire Events - Trélazé

Discover the diverse range of events at Arena Loire in Trélazé, from spectacular concerts to major sporting events.

Trélazé borders the city of Angers in the Maine-et-Loire department and is historically synonymous with slate mining. For centuries, it served as the center of the French slate industry, supplying the black rock that covers the roofs of countless Loire Valley châteaux. The realities of the miners' lives and traditional stone splitting techniques are documented at the local Slate Museum (Musée de l'Ardoise). Today, the extensive former quarries have been rehabilitated into the Parc des Ardoisières, a vast nature reserve. This post-industrial landscape has striking visual contrasts, featuring sheer rock faces, deep flooded excavation pits, and specialized flora that has reclaimed the rocky terrain. The park's rugged paths draw hikers, runners, and photographers looking for unconventional scenery. Trélazé has also emerged as a cultural venue, anchored by the Arena Loire, which hosts major indoor concerts and sporting events. The town's streets still feature rows of modest 19th-century workers' housing. It stands as a fascinating example of how heavy industrial heritage can be transformed into a thriving ecological space.
