Since the 13th century a small church, dedicated to the Virgin, was known here, that developed into a place of pilgrimage. Rich donations made the erection of the church seen today possible. The construction started in 1405 and was completed in 1527.

Basilique Notre-Dame, located in a village (pop. ~600), is about 59 metres long. There is a replica of the miraculous statue of the Virgin. According to a legend the statue was found by shepherds in the Middle Ages in a burning thorn bush.

The basilica´s inner and outer walls are dotted with names. Pilgrims have carved in these graffiti over centuries.
