A prison cell until 1824, this room which is the most squalid of the whole house was given free of charge to the Soubirous family. They stayed there from winter 1857 to the autumn of 1858. It was from there that Bernadette went to the Grotto to meet the Virgin Mary on eighteen occasions. Recently renovated one can see in all its bleakness this room of 3.72m by 4.40m, which served at the same time as a kitchen, dining room, bedroom and a place of prayer for six people.
