The Gauls, Romans, Barbarians and Moors successively fortified the rock of Lourdes, where the Château-Fort castle stands.
Since the 9th century, the town has been governed in turn by the English and then by the French. During the religious wars of the 16th century, it was sacked by the Huguenot troops.
In the 17th century, Bigorre’s unification with France (1607) along with progress made in the use of weapons meant that the citadel became less important. It kept a small garrison and became a State prison (castle).
Lourdes came through the French Revolution (1789) without too much damage, and became an agreeable small town in the 19th century. In the early 1850s, the castle was occupied by an infantry garrison. Back then, the town was just a stopping place for spa visitors, who were attracted by the water at Barèges, Cauterets, Luz-Saint-Sauveur and Bagnères-de-Bigorre, and for the first Pyreneists on the way to Gavarnie. Lourdes was only the modest administrative centre of a canton of 4135 inhabitants.
Among them were François and Louise Soubirous, who lived at Boly mill for 10 years with their four children, the eldest of which was named Marie Bernarde, known as Bernadette (born on 7 January 1844).
