La Chapelle de Garreau is located in La Chapelle-Hermier in the place called "Le Garreau". It is the busiest pilgrimage center in the lower maritime Vendée. Louis XIII would have come there after his victory over the Protestants at Riez.
Legend has it that a monk would have seen an apparition of the Virgin Mary, washing clothes in the waters of Jaunay. The chapel would therefore have been built in memory of this apparition.
A pilgrimage is held there on the first Sunday of September. If the crowds are considerably reduced today, until the 60s it brought together devotees from all over the department.
