Hamlets of Leÿ and Messy

The viaduct of Mieussy was built in 1931, it is 126 meters long, and has a central 24 meters arc. The maximal height is 20 meters. Before, it allowed the passage of a train connecting Annemasse and six.In 1891, a railroad line was opened between Annemasse and Samoëns, serving most of the valley's communes. At the time, the 49-kilometer route could be covered in three hours by steam streetcar, twice as fast as by stagecoach. In 1933, the line was electrified and extended as far as Sixt-Fer-à-Cheval, providing a complete service to the valley. This modernization led to a significant increase in ridership. In winter, the line was used extensively by the people of Geneva, who could take it from Annemasse to reach the mountains and even go skiing. Railway workers were faced with tough working conditions to clear the snow from the tracks. Despite this, in 1946 the section between Saint-Jeoire and Marignier was closed, and ridership continued to fall over the years. In 1959, the line finally closed for good, as the work required to renovate it could not be financed. Since then, the line has been operated by bus. At Mieussy, a 126-meter-long viaduct built in 1931 remains. Forbidden to motorized vehicles, it can only be used on foot or by bicycle.

It was founded in 1662 by Claude Bailly, a notary from Leÿ. In 1837, it was restored thanks to a bequest from Jean François Leyat, hence the inscription "JFL 1837".In 1868, the villagers joined forces to buy a chalice, which they now owned. Previously, they had built a bell tower, with a bell that was rung three times a day for the Angelus, and the altarpiece depicted the angel Gabriel announcing to Mary that she would be the mother of the Savior. A special feature of this chapel is that the side windows are hidden by shutters. A final restoration was carried out in 1939. In 2008, Raymond Blanc donated paintings to the chapel, including copies of works by Arcabas from the church of Saint Hughes en Chartreuse.
