Originally, there was a Romanesque chapel in the hamlet of Roselend. It was dedicated to Saint Mary Magdalene. A 13th-century document mentions a chapel that could be this one. More precise sources indicate that the bell was cast in 1608 or that donations were made in 1710, 1757, and 1760. In 1794, it hosted four émigré priests from the valley for their first mass after their return from exile, including the future Archbishop of Chambéry, Antoine Martinet. Submerged when the dam was filled on May 6, 1960, a chapel was rebuilt two years later near the road overlooking the lake, in a more modern style.
