Fort du Lourdou, an ancient outpost
Nestled atop the imposing cliffs of Roc d’Anglars, some fifty metres above the meandering Aveyron River, stands the medieval Fort du Lourdou, also known as Fort du Roc d’Anglars. This ancient outpost, erected in the 5th century, provided the main defence for the fortress of Belcastel during the tumultuous Visigoth invasions.

Originally circular in shape, with a diameter of 20 metres, the fort extends over several levels, finely fortified and protected by imposing ramparts and trenches. Its layout, characterised by interconnected structures and labyrinthine passageways, was strategically designed for optimal defence in case of attack.
Belcastel, located just 500 metres downstream, derives its name not from its aesthetic appeal (“beautiful castle”) but rather from its historical function as a “war castle” – “bellum castle”. Today, this charming medieval village is renowned as one of the most picturesque destinations in France.
A well-marked trail, starting in the village and winding through verdant meadows and crossing a rustic wooden footbridge, will lead you to Fort du Lourdou.
Fort du Lourdou oratory
The Fort du Lourdou takes its name from a nearby grotto dedicated to the Virgin Mary. Inspired by the resemblance of this natural cavity to the famous grotto of Massabielle in Lourdes, where the Virgin Mary is said to have appeared to Bernadette Soubirous in 1858, Father Gély, the priest from Belcastel, christened it “Lourdou” in the local dialect.

Driven by a profound faith and eager to honour this sacred place, Father Gély meticulously transformed the humble cave into a rural oratory. Adorned with an altar, a statue of Our Lady of the Immaculate Conception, and a space for lighting candles, the oratory became a sanctuary for contemplation and prayer. In 1889, Father Gély celebrated the inaugural Mass there.
A wooden footbridge provides access to the path leading to the oratory and the summit of Roc d’Anglars. This path is marked with wooden crosses, each representing one of the twelve stations of the Way of the Cross.
