It was at the Moulin de Boly that Bernadette Soubirous was born on January 7, 1844. She lived in the mill with her parents for 10 years. She will call it "the mill of happiness". It was part of the time of the many water mills located along the creek "Lapacca" (channeled today under the Boulevard de la Grotte) and flowing into the Gave de Pau. Inside, you will discover the room where Bernadette was born, the kitchen and the old mill and its millstones (restored in 2012).
